摘要: Photoluminescent, undoped ZnO films have been fabricated using spray pyrolysis of zinc nitrate solution. The luminescent had a polycrystalline hexagonal wurtzite type structure with no preferred orientation. Photoluminescence intensity was critically dependent on substrate temperature during and post-annealing temperature. Green, photoluminescent possessed porous while orange close packed granular morphology. Green luminescence appears to be due oxygen vacancies in layer just below the crystallite surface.
