硫化物纳米级粒子化膜的形成与气相性质的影响

The Generation of Nano-Size Sulphide Particles by Chemical Reaction in Insoluble Film and the Effect from Gas Phase

采用偏振光反光度、紫外及可见光谱、电子显微镜形貌观察、粒子大小测定及电子衍射等方法加以系统研究硫化锌纳米级粒子化膜的制备与气相性质的影响．

The generation of nano-size particles by chemical reaction is a new method with advantages, which provides nano-size particles in a form of thin film called particulate film. Since the chemical reaction takes place at surface, it would be effected by the physicochemical properties of the gas phase, liquid phase and surface phase. In this work, light reflectivity measurement, transmission electron microscopy, UV-visible spectroscopy and electron diffraction technique have been used to investigate the effects of the properties of gas phase on the particulate film formation of ZnS.
