用反应蒸发法制备氧化锡薄膜,对各样品取相同的制备条件,然后,进行不同的后处理,用扫描电子显微镜观察各样品的表面形貌,分析研究,进行了初步探讨。 The SnO2 thin films were prepared by reactive evaporation method. The same preparation conditions were taken for each sample. Then, different post-treatments were carried out. The surface morphology of each sample was observed by scanning electron microscopy, and the preliminary study was carried out.
