Abstract

Abstract: ZnO nanoorystals thin film were prepared by means of the self-assembly mothed.The complex films of mercaptoacetic acid(MPA)and ZnO nanocrystals(ZNCs) were prepared by means of the self-assembly technique.The interaction between the MPA and ZnO within the MPA and ZnO nanocrystal thin film decreases the photoluminescence intensity of the ZnO.The interaction was manifested by the X-ray photoelectron spectra.The intensity change of the photoluminescence of the ZnO is discussed on the basis of taking into account the process of electron transfer on the interface between the ZnO and MPA.The electron transfer of ZnO depends on the distance between the ZnO and MPA.

Key words: ZnO, Mercaptoacetic acid, Electron transfer
