摘要

用热蒸发CVD法制备了-Ga

纳米材料

探讨了Au催化剂对纳米结构和形貌的影响

并研究了其光致发光特性。X射线衍射(XRD)分析显示产物为单斜结构的-Ga

。扫描电子显微镜(SEM)测试表明:Au催化剂颗粒尺寸较小时

制备的产物为尺度均匀的-Ga

纳米线

宽度小于100 nm

长度为几微米至几十微米;增加催化剂颗粒尺寸时

制备出的-Ga

纳米结构的尺度变大

形貌由纳米线逐步形成纳米带、片等形状。-Ga

纳米结构在波长516 nm处有很强的绿光发光带

而且随着催化剂颗粒尺寸的增加

发光强度和峰位"红移"现象逐渐减弱。

Abstract

The beta-gallium-oxide (-Ga

) nano-material was prepared from gallium and oxygen by thermal evaporation in the argon atmosphere. The X-ray diffraction (XRD) reveals that the synthesized products are monoclinic gallium oxide. When the sizes of Au catalysts are small

the breadths of the nanowires are less than 100 nm and the lengths are several micrometers. With the increasing of the catalyst particle sizes

the morphology of the products are gradually transformed into nanobelts

sheets and other shapes. -Ga

has stable emission at 516 nm under excitation of 325 nm. With the increasing of the catalyst particle sizes

the luminescence intensity and the red-shift are gradually weakened.
