| 摘 要： | 采用溶胶-凝胶法在铟锡氧化物(ITO)导电玻璃基底上制备了不同掺杂浓度的Cu∶ ZnO薄膜.采用X射线衍射仪和扫描电子显微镜分析了薄膜样品的晶相结构和形貌,用荧光光谱仪测量了薄膜样品的光致发光谱.结果表明:Cu∶ ZnO薄膜均为六角纤锌矿结构,呈c轴择优取向,且因压应力的存在使其晶格常数略小于未掺杂薄膜样品的晶格常数；低温和高温退火处理的薄膜样品的光致发光谱(PL)中分别观察到414 nm、438 nm的蓝光双发射峰和510 nm左右的绿光发射峰.蓝光发射峰与样品中的Vzn和Zni有关,而绿光发射峰与样品中的Vo -Zni有关.

| Abstract: | Cu doped ZnO thin films with different doping concentrations were prepared on indium-doped tin oxide(ITO) conducting glass substrates by sol-gel technique.The crystalline phase structure and surface morphology of the films were analyzed by X-ray diffraction and scanning electron microscope.The photoluminescence spectra of samples were measured by fluorescence spectrophotometer.The results show that these films have a compact hexagonal wurtzite type structure and high c-axis preferred orientation.Lattice con... |
