| 摘 要： | 用热蒸发法成功地在玻璃、硅和铝等衬底上沉积新型四羧基合铜化合物ＣｕＢ（Ｂ为有机配体甜菜碱）薄膜．通过对比薄膜与粉末原料的红外吸收光谱图，确认薄膜物质成分与结构未发生变化；电子探针分析结果表明薄膜的元素空间分布均匀．用金相显微镜、扫描电镜对薄膜的表面形貌进行了研究；并测量了膜的电导温度特性、紫外可见吸收光谱和荧光光谱．结果表明，所制备的薄膜是具有很宽禁带宽度（Ｅｇ＞６ｅＶ）的绝缘体，带隙中具有３个能级，测得荧光发射的特征波长为４０９ｎｍ．

| Abstract: | Details are given of an experimental study on the deposition process of Cu(bet) 4](ClO 4) 2(bet=betaine) thin films and their optical and electrical properties It is demonstrated that such films may be prepared using thermal evaporating technique The films were characterized by using infrared spectroscopy, electron probe microanalyses (EPM) and scanning electron microscope Similar infrared spectra were obtained between the films and powders Results of EPM show that each element of the chemical composition was distributed evenly in the surface of the films In addition, the electrical conductivity, optical absorption and fluorescent spectra of the film were measured The results reveal that this type of films is a wide band gap insulator Significant fluorescence was detected and the spectrum with peak at 409nm was recorded |
