以SnCl4·5H2O,FeCl3·6H2O及无水乙醇为主要原料,采用溶胶凝胶法制备了SnO2∶Fe2O3混合薄膜,测量并研究了其在可见光区附近的丙酮气敏反射光谱。
SnCl 4 · 5H 2 O, FeCl 3 · 6H 2 O and ethanol were used as raw materials to synthesize SnO 2: Fe 2 O 3 films by sol-gel method. The acetone gas sensing spectra were measured and studied in the vicinity of visible light.
