CuLaO2;  magnetron sputtering;  Photoluminescence

Pure phase CuLaO2 powder was prepared by traditional solid phase sintering method, and CuLaO2 film was prepared by RF magnetron sputtering method for the first time and annealed, and CuLaO2 film with a small amount of heterophase was obtained. Its transmittance is higher in the infrared light region, nearly 70%, and the visible light is lower in the Itt phase.The conductivity of CuLaO2 film is about 6.7×10-4S/cm.The photoluminescence performance of CuLaO2 powder and film at room temperature was compared and analyzed.The test results show that the powder and film have obvious luminescent bands in the range of 450 am-650 am, while the film has a small amount of heteropeaks, which are due to the influence of La203, Cu oxide and quartz substrate.
