通过对用化学溶液法制备硫化镉薄膜的微观生长过程和机理的研究， 建立一种在溶液中进行超声波化学制备硫化镉半导体薄膜的方法． 用扫描电子显微镜对化学溶液法和超声化学法沉积的硫化镉薄膜的生长过程进行跟踪观察． 讨论了硫化镉薄膜的 Ｕ Ｖ可见光谱 Through the study of microscopic growth process and mechanism of CdS thin films prepared by chemical solution method, a method of ultrasonic chemical preparation of CdS semiconductor thin films in solution was established. Scanning electron microscopy was used to observe the growth of cadmium sulfide thin films deposited by chemical solution and sonochemical methods. The UV-visible spectrum of CdS films is discussed
