摘　　要：介绍了用溶胶凝胶法制备二维Ｖ２Ｏ５光学薄膜，并研究其在氨气、乙醇、丙酮、丁烷气氛中的气敏反射特性，发现对氨气有极好的选择性，且气敏性在整个可见光波段有良好的单值性，是一种有实用价值的气敏光纤传感材料。Considering V 2O 5 as a gas sensing materials,we successfully manufactured 2 dimensional V 2O 5 film by Sol Gel method.The gas sensing reflective spectra in ammonia,alcohol,acetone and butane vapor are experimentally studied.The experiments show that the film has good gas selectivity and monotonicity of the response curve in whole visible spectrum to ammonia.So the film can be used in optical fiber gas sensing head.
