摘要 用化学水浴法在玻璃衬底上沉积ZnS薄膜。采用XRD、SEM、nkd-薄膜分析系统对薄膜的形貌、结构和光学性能进行了分析,结果表明:当氨浓度〈1.50mol/L,可获得白点较少、平整性较好的非晶ZnS薄膜,在红移方向上很长的波段内透过率较好,可达95%以上,禁带宽度为3.81eV,折射率随波长的增加而减小,从2.32变化到1.92。有关化学水浴ZnS薄膜折射率的报道极少;当氨浓度〉1.50mol/L时,薄膜白点增多,易龟裂和剥落,结构是立方闪锌矿。 ZnS thin films have been deposited on glass substrats by chemical bath deposition(CBD) method.The morphological, structural and optical properties of ZnS thin films have been investigated by SEM, XRD and nkd- spectrophotometer. When NH3 concentrations is no more than 1.50mol/L, good leveling and uncrystalline of ZnS thin films have been prepared. Transmission of ZnS thin films is larger than 95% in medium and long wave. A direct band gap is 3.81eV, the values of refractive index range from 2.32 to 1.92 and its values has been reported very less before. When NH3 concentrations is more than 1.50mol/L, ZnS thin films are chapped and shelled of from the glass substrats. At the same time, the proper pH of thin film deposition is about 10-11.5.
