Photonic　crystals　can　effectively　modulate　infrared　spectral　properties.　In　this　paper,　a　one-dimensional　photonic　crystal　of　multilayer　Cu/CuO　is　proposed　to　achieve　selective　infrared　radiation　within　atmospheric　windows.　A　multilayer　Cu/CuO　with　a　periodic　structure　was　designed　via　the　transfer　matrix　method　and　prepared　via　reactive　sputtering.　The　results　of　emissivity　measurement　showed　that　the　Cu/CuO　one-dimensional　photonic　crystals　with　2???4　periods　and　a　certain　thickness　exhibited　good　infrared-selective　properties,　with　average　emissivities　of　0.1　and　0.9　at　wavelengths　of　3???5　and　8???14　??m,　respectively;　thus,　the　Cu/CuO　onedimensional　photonic　crystals　have　potential　applications　as　infrared　spectral　modulation　materials.
