从NaOH和LiOH的混合碱液中生长了具有不同六方形貌的淡黄色ZnO晶体.采用X射线粉末衍射的方法对晶体的物相进行了分析,利用光学显微镜和扫描电镜对晶体的形貌进行了表征,同时利用电子探针能谱仪对晶体的组分进行了分析.从晶体的室温光致发光谱图中可以观测到380,445,512,652 nm处存在与晶体结构和缺陷相关的发射峰.

Transparent pale yellow ZnO crystals with different hexagonal morphology,such as hexagonal caps and hexagonal lamellae,have been successfully synthesized in molten hydrous NaOH-LiOH.The phase structure of the as-grown crystals was investigated by means of X-ray powder diffraction.Detailed surface morphology of the crystals was studied using optical microscopy and scanning electron microscopy.Elemental analysis of the synthesized crystals was performed using energy dispersive X-ray spectrum.The photoluminescence spectrum was employed to characterize the obtained crystals.Some ultraviolet,blue,green and red emission peaks were observed in the photoluminescence spectrum.
