摘要：

Zn0.9Co0.1O　powders　are　compounded　by　the　solid　state　reaction　and　prepared　for　the　high-quality　target　of　depositing　films.　Zn0.9Co0.1O　powders　are　synthesized　at　various　fritting　temperatures　in　order　to　investigate　the　structural　and　optical　properties　of　the　powders.　The　structural　properties　of　a　nubby　powder　are　measured　by　X-ray　diffraction　(XRD).　The　optical　properties　of　the　target　are　tested　by　Raman　scattering　and　ultraviolet　photoluminescence　(PL)　emission　measurements,　respectively.　The　results　show　that　the　fritting　temperature　is　an　important　parameter　to　influence　the　sample　structure.　A　series　of　Co　substitute　Zn　and　the　sample　retains　original　structure　in　wurtzite　lattice　with　a　temperature　of　1200°C.　At　the　same　time　the　band　gap　of　ZnO　crystal　lattice　is　narrowed　from　the　Raman　spectrum.
