In　this　paper,　pulsed　laser　deposition　method　was　applied　to　grow　ZnO　films　in　different　temperature,　with　ZnO　ceramics　as　target,　sapphire　Al2O3　(0001)　for　substrate,　and　using　the　pulsed　laser　GCR-170　Nd:YAG　by　Spectra-Physics.　The　thin　film　structure　and　superficial　morphology　quality　have　been　researched　in　experiment　by　atomic　force　microscope　(AFM),　photoluminescence　(PL)　and　optical　transmission　spectrum,　and　optimize　growth　temperature　was　found　to　be　500C　at　which　the　ZnO　films　could　obtain　high-quality　surface.　The　high　violet　light　radiation　have　been　found　in　experiment.　The　optical　transmission　spectrum　versus　the　substrate　temperature　results　showed　that　for　the　ZnO　thin　films　prepared　on　sapphire,　the　surface　morphology　quality　of　the　ZnO　thin　film　was　enhanced　with　increasing　the　substrate　temperature　from　room　temperature　to　500C.
