摘要

采用拉曼显微镜和光谱技术对金属离子(La、Cr、Al、Fe和Sm)掺杂ZnO制备纳米结构薄膜进行了详细的研究。讨论了室温下$\lambda=532 \ nm$激发下的拉曼光谱。通过对拉曼模式的频率、线宽和半峰宽(FWHM)的分析，揭示了金属掺杂剂的性质对ZnO纳米结构薄膜纤锌矿晶体结构的影响。

A Raman spectroscopy focused study of the metal dopant effect on ZnO nanostructured thin films

A detailed Raman microscopy and spectroscopy study of metal ions (La, Cr, Al, Fe and Sm) doping of ZnO as nanostructured thin films prepared by spray deposition method is presented. Raman spectroscopy performed under $\lambda=532 \ nm$ excitation at room-temperature is discussed. In particular, analysis of the frequencies, linewidths and width at half maximum (FWHM) of the Raman modes to show the influence of nature of metal dopants effects on the wurtzite crystalline structure of the ZnO nanostructured thin films.
