Abstract	The effect of post deposition annealing in air on structural, electrical and optical properties of Er,Licodoped ZnO films deposited on sapphire substrate by an e-beam evaporation technique in vacuum are investigated. The structural, optical and electrical features of these films before and after short-time annealing were studied by XRD, UV-VIS-IR absorption and reflection spectroscopy, photoluminescence and resistivity measurements. Experimental results showed that there is wide absorption band in IR range, connected with defect centers, presumably OH-complex, in as-deposited films, and after annealing it is disappeared. Green and NIR photoluminescence of Er3+ ions in annealed films excited under nitrogen laser was observed. The intensity of photoluminescence is much stronger for sample with Li (0.8 %) than that with Li (0.6 %).
