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.

Key words: Chemical reaction at insoluble monolayer, Nano-size particulate film, Zinc sulphide, Arachidic acid
