Abstract ：
采用脉冲激光沉积技术在真空腔中制备了ZnSe∶Co薄膜.研究了沉积压强对等离子体羽辉传播、薄膜表面形貌,微结构以及光学性质的影响.结果表明,随着压强的增大,等离子体羽辉在空间的传播距离减小,薄膜沉积方式由溅射式沉积转变为吸附式沉积,薄膜的结晶质量得到大幅提升.此外,薄膜的光学带隙随压强的增大而减小,低压条件下制备的薄膜具有较大的带隙值,这与量子限域效应有关.当压强增大到10 Pa时,得到了沿(111)方向择优生长且结晶质量优秀的微晶薄膜.

Abstract ：
Real-time monitoring of environmental relative humidity (RH) plays a crucial role in ensuring both the quality of industrial production and the quality of life. In this work, polarization maintaining fiber (PMF) was used as carriers to creatively constructed multi-layer film surface functionalization on its cladding surface. The indium tin oxide (ITO) film and polyvinyl alcohol (PVA) doped graphite oxide (GO) composite polymer constitute multilayer humidity sensitive film, which has the effect of dual absorption of water and improves the humidity sensitivity. Microporous composite polymer films created by laser processing increase the area for water evaporation and absorption, which improve response speed, and reduce recovery time. The surface functionalized PMF sensor exhibits high sensitivity and rapid response to humidity, achieving bidirectional repeated measurement of 0.28 nm/% within 10 s in the measurement range of 30%-90%, rendering it a reliable means for realtime monitoring of humidity.

Abstract ：
The rapid, portable, and in situmeasurement of the ascorbic acid(AA) solution remains a challenge, and there is no suitable way toachieve multiscale regulation of the measurement range and sensitivity.In this work, water-soluble CdTe, CdTe/CdSe, and CdTe/CdSe/ZnS quantumdots (QDs) were used as fluorescence probes (FPs), and the specificsensitivity of photoluminescence (PL) intensity and AA were used asa detection indicator. By changing the concentration of the FP andthe type of core-shell structure, multiscale regulation ofthe measurement range and sensitivity was realized. The same FP withdistinct sensitivity in different measurement ranges is ingeniouslyrealized by double-layer core-shell CdTe/CdSe/ZnS with typeII-I band gap transition, which greatly expanded the application fields.The maximum measurement range was 0-27 & mu;M and the minimumdetection limit was 0.014 & mu;M for three FP systems. The capillarysensor with a honeycomb QD film attached to the inner wall was preparedby drying at room temperature, high-temperature heating, and laserprocessing, which greatly increased the contact area between the QDsand AA and reduced the measurement time. Furthermore, the microfluidicsystem was used to precisely control the deposition area and positionof the film, the concentration of the FP was adjusted and the depositionstatus of the film was observed in real time, so as to achieve real-timein situ rapid detection of the four concentration orders of the AAsolution. This work is of great significance for the rapid, portable,multifield, and in situ real-time detection in the field of biomoleculedetection.

Abstract ：
采用脉冲激光沉积技术在石英基片上制备了ZnS:Co薄膜，改变制备过程中石英基片的温度TS，研究了基片温度对薄膜微结构及光学特性的影响。随着基片温度的升高，薄膜的厚度减小，结晶质量得到提升，并朝着（111）方向择优生长。受量子限域效应的影响，薄膜的光学带隙在基片温度为TS=25℃时最大为3.83 eV，光学带隙先随基片温度增大而减小，并在基片温度为400℃时取得最小值3.5 eV，此后随基片温度增大而增大。此外，薄膜的折射率、消光系数、介电系数等光学参数随基片温度升高均有增大趋势。实验表明在基片温度达到400℃以上时，可以获得综合性能较好的微晶薄膜。

Abstract ：
Multi parameter measurement based on optical fiber sensor has been a research hotspot in recent years. In this work, four kinds of optical fiber sensors, LPFG, FBG, PMF and SMS are used. The transmission characteristics and sensing characteristics of each sensor are analyzed in detail. Based on the modulation of resonance wavelength by environmental variables, the accurate and synchronous real-time detection of temperature, stress, refractive index and humidity is realized. We use all-optical coupling cascade and wavelength division multiplexing (WDM) technology to prepare a highly integrated sensing device. The problem of signal crosstalk of each sensor is solved, and the cost of signal transmission and reception is greatly reduced. It is of great significance for monitoring a variety of environmental variables under extreme conditions.

Abstract ：
Optical modulation is the process of modifying the structure and elemental composition of materials so that the main optical parameters, including amplitude, frequency, and phase, are changed. Currently, much research attention has been directed toward ultrafast dynamics, but the process of modulation is often complex. To simplify the optical modulation process and improve the optical properties of perovskites for semiconductor quantum dot (QD) lasers, the process and physical mechanism underlying graphene QD ultrafast modulation of the optical properties of perovskite CsPbBr3 QDs were investigated. The typical cubic structure and square shape of CsPbBr3 QDs were characterized by transmission electron microscopy and X-ray diffraction, respectively. A luminescent peak centered near 540 nm and Stokes shift of 21.34 nm of CsPbBr3 QDs without graphene QDs were measured by absorption and photoluminescence spectroscopy. A maximum modulation shift of 133 nm and a modulation depth of 900% were achieved in CsPbBr3 with graphene. The results indicated that graphene QDs had the best modulation effect on perovskites when the drop volume was 0.05 mL. The process of ultrafast optical modulation via graphene QDs occurring within 1 ps was confirmed by the transient absorption spectrum. The modulation mechanism of graphene to perovskites is presented for guidance. This paper can be used as a reference for the optical modulation of perovskite materials.

Abstract ：
In this work, the surface of long-period fiber grating (LPFG) and polarization maintaining fiber (PMF) is functionalized based on the interaction between the resonance wavelength and external environment. LPFG coated with a 150 nm ZnSe/Co film is fixed on a hollow bracket, prestressed, and annealed many times. A highly sensitive liquid level sensor with adjustable sensitivity, an adjustable measurement range, and a high liquid level early warning is prepared. The waveguide layer controlled by humidity is constructed by filling poly(3,4-ethylenedioxythiophene)/poly(styrene sulfonate) (PEDOT/PSS) in a periodically etched PMF. The surface is coated with a poly(vinyl alcohol) (PVA) and carbon nanotube (CNT) composite polymer. After laser processing, a honeycomb porous film is obtained, and the humidity sensor with wavelength modulation is prepared. The pH-sensitive polymer is successively adsorbed on the surface of PMF coated with a 120 nm indium tin oxide (ITO) film by electrostatic self-assembly (ESA). Poly(allylamine hydrochloride) (PAH), poly(acrylic acid) (PAA), and poly(styrene sulfonate) (PSS) constitute a composite film with rapid deposition and high permeability that is covered with polyaniline/poly(methyl methacrylate) (PMMA) as the protective layer. After laser processing, a fluffy porous film structure is formed. The pH sensor is obtained and the preparation steps are greatly reduced. Finally, based on the wavelength division multiplexing (WDM) and multiwavelength matrix (MWM), the problem of crosstalk is solved. An integrated sensor is constructed to realize the simultaneous measurement of temperature, liquid level, humidity, and pH. It has been successfully applied to monitor the overall environment of a chemical waste liquid storage tank. The sensor has the advantages of remote monitoring, safety, efficiency, and labor-saving. © 2022 American Chemical Society.

Abstract ：
Increasing sensitivity, measuring points, and stability have always been the pursuit of sensors. ZnSe9:CO1 and Ag composite nano films were coated on polarization maintaining fiber (PMF). Then, the coated PMF was nested in capillary and hose which was encapsulated with polydimethylsiloxane (PDMS) and epoxy resin. The integrated capillary sensor and thermoplastic hose sensor were prepared. The gradient sensitization of various measurement parameters such as temperature, stress, and micro bending is realized. The temperature sensitivity is 1.49 nm/degrees C, the micro bending sensitivity is 1.72 nm/10(2) g, and the stress sensitivity is 6.27 nm/m epsilon. The sensors maintain good linearity and instantaneous response while having high sensitivity. By adjusting the length of PMF, the number of troughs is increased in the same band range, and different troughs have different sensitivities, which solves the inherent problem of cross sensitivity and realizes multiparameter measurement. Capillary sensors are used for remote safe real-time monitoring of mechanical overheating, and hose sensors are used for real-time monitoring of bridge load and human joint bending. This work is of great significance to the extension of the application range of optical fiber sensor.

Abstract ：
In this paper, the graphene tilted Bragg fiber grating (TFBG) sensor is fabricated by pulsed laser deposition (PLD). TFBG's sensitivity to external environmental changes can be improved to a certain extent by coating graphene in TFBG area. The experimental results show that the strain sensitivity of TFBG coated with graphene is 0.48 nm/m epsilon, which is 1.6 times of the strain sensitivity of bare grating. The temperature sensitivity of TFBG coated with graphene is 0.1 nm/degrees Cas same as bare grating. Based on the dual-wavelength matrix method, the Sagnac loop is used to cascade the coated tilted grating with The Bragg grating (FBG), and the temperature and stress sensing characteristics are measured simultaneously.
