采用简单、廉价的溶胶-凝胶旋涂技术制备了纳米SnO2薄膜，并在350℃和450℃两种不同温度下对薄膜进行了热处理。用X射线衍射仪、傅里叶变换红外光谱、紫外可见光谱、荧光光谱和循环伏安法对薄膜的结构、振动、光学和电化学性质进行了分析，并对结果进行了详细的讨论。采用琼脂琼脂法对SnO2薄膜的抑菌性能进行了研究，结果证实了SnO2薄膜对大肠杆菌和芽孢杆菌的抑菌活性。(C)2015爱思唯尔B.V.保留所有权利。
Nanocrystalline SnO2 thin films were deposited by a simple and inexpensive sol gel spin coating technique and the films were annealed at two different temperatures (350 degrees C and 450 degrees C). Structural, vibrational, optical and electrochemical properties of the films were analyzed using XRD, FTIR, UV Visible, fluorescence and cyclic voltammetry techniques respectively and their results are discussed in detail. The antimicrobial properties of SnO2 thin films were investigated by agar agar method and the results confirm the antibacterial activity of SnO2 against Escherichia coli and Bacillus.
