The results of XPS show that those two kinds of film consist of Cd and CdS and their mole ratio is about 2:1. The analysis of XRD indicates that nanofilm deposited under the optimum condition consists of polycrystalline of Cd and CdS.

• 两种情况下制得的薄膜 XPS 图谱表明薄膜含有镉和硫化镉,单质镉和硫化镉的 mol 比近似 2:1。 通过 XRD 对最佳工艺制备的纳米膜进行结构分析表明纳米膜由单质镉和硫化镉混合晶构成。
