N2 - Lithium doped zinc oxide photoluminescent films have been prepared by the spray pyrolysis technique. All deposited films show a hexagonal polycrystalline structure. The optical transmission depends on the substrate temperatures (Ts) which show an absorption edge shifting to longer wavelengths with higher Ts. The photoluminescence spectra of samples deposited at low Ts show two emissions located at 420nm and 500nm, associated with te blue emission of the pyrex glass substrate and the blue green emission characteristic of intrinsic zinc oxide, respectively. Films deposited at high Ts show a light emission peak at 555nm. This later peak seems to be associated with the incorporation of Li in the ZnO film.
