作者研究了二氧化锡的气敏光反射特性,测量了它在乙醇,氨,丙酮气体中的浓度与气敏反射光谱关系,发现它对氨气的气敏光谱波长灵敏范围最大,而且不同波长有不同的灵敏度。解释SnO_2气敏光反射机理。
The authors studied the gas-sensing light reflectance characteristics of tin dioxide and measured the relationship between its concentration in ethanol, ammonia and acetone gas and its gas-sensing reflectance spectra. It was found that the sensitivity range of gas sensing wavelength to ammonia gas was the largest, Different sensitivity. Explain SnO 2 gas sensitive light reflection mechanism.
