摘    要:采用高分子网络原位合成法制备了ZnO/PVP纳米复合膜.并且通过多种测试手段对ZnO/PVP纳米复合膜的光学特性进行了分析.通过XRD,TEM的测试结果可知,以聚乙烯吡咯烷酮(PVP)为模板,原位合成ZnO纳米粒子,具有六角纤锌矿结构;分散性好,粒径分布窄等特点;从光致发光谱中可以看出由于PVP的引入,使得ZnO纳米粒...

关 键 词:薄膜  氧化锌  光致发光

Abstract:We fabricated a inorganic-polymeric photoluminescent thin film based on ZnO nanoparticles,which were grown directly in the poly(vinylpyrrolidone)(PVP) polymer matrix.The optical characteristics of the thin film were investigated.Result: X-ray diffraction(XRD) and transmission electron microscopy(TEM) indicated that all the ZnO nanoparticles were well separated from each other and were dispersed in the polymeric matrix homogeneously and randomly with a polycrystalline hexagonal wurtzite structure.The photoluminescent spectrum(PL) of the ZnO nanoparticles modified by PVP molecules showed markedly enhanced ultraviolet emission and significantly reduced green emission,which was due to the pefect surface passivation of ZnO nanoparticles.Temperature dependent photoluminescent spectrum studies suggested that the ultraviolet emission was associated with bound exciton recombination.
Keywords:thin film  ZnO  photoluminescence
