氨水浓度对化学浴沉积的Zn(O,S)薄膜形貌、结构和性能的影响
Influence of Ammonia Concentration on Morphology, Structure and Properties of Zn( O, S) Films Prepared by Chemical Bath Deposition
摘要
Abstract
The Zn(O,S) thin films were prepared by chemical bath deposition (CBD) using ZnSO4 o 7H2O and SC(NH2)2 as the precursors, C6H5O7Na3 o 2H2O as the complexing agent, NH3 o H2O as the auxiliary complexing agent and buffer agent. The obtained thin films were characterized by scanning electron microscopy (SEM) , energy dispersive spectrometer (EDS) , X-ray diffraction (XRD) and UV-Vis spectrophotometry. The morphology, structure and optical properties of Zn (O, S) thin films were investigated as a function of ammonia concentration in precursors. The results reveal that Zn( O,S) films are composed of ZnO nano-particles and ZnS nano-particles. ZnO is wurtzite structure and ZnS is amorphous. As the ammonia concentration decreasing, the proportion of ZnO decreases while that of ZnS increases gradually. In the meanwhile, S/Zn atom ratios, transmission and optical band gap all increase.关键词
