Abstract：
Eu2+doped Sr2Al2SiO7luminescent materials were prepared by sol-gel-combustion reduction method under the condition that the reaction temperature is 1100 and the pH is 3 to 4. The crystal structure and the luminescent properties of the samples were characterized and measured by using the method of TG-DTA, XRD and fluorescence analysis., respectively. The results showed that Sr2Al2SiO7: Eu2+luminescence materials exhibited tetragonal system crystal structure, and its excitation spectra was a broadband spectrum located at 344 and 350 nm. The emission spectrum is located at 455 nm, the maximum luminous intensity is 7500 mcd; The Eu2+doped concentration had large effects on luminescent properties of the prepared material. The intensity of excitation and emission spectrum arrived at the maximum when doped molar concentration was 0.04. © 2015, Editorial Office of ＇Chinese Rare Earths＇. All right reserved.
