需要对硫化物气体进行监测，以保护生物体免受其毒性影响。金属氧化物的纳米颗粒具有可用作控制环境污染如硫化物气体的传感器的特性。采用化学液相沉积法制备了SnO 2薄膜作为硫化物气敏元件的组成部分，并利用UV/维斯/NIR分光光度计、FTIR、SEM和XRD等手段对薄膜进行了表征。表征研究显示纳米颗粒的尺寸在38-71 nm的直径范围内。将SnO 2薄膜应用于紫外/维斯/NIR漫反射光谱仪检测硫化物气体中，发现SnO 2薄膜在1428 cm波长处的最大% R峰发生了位移，表明SnO 2薄膜与硫化物气体发生了化学反应。使用这种SnO 2纳米薄膜测量硫化物气体的好处是它可以在室温下完成。
Sulfide gas monitoring is required to protect organisms from its toxicity. Nanoparticles of metal oxides have characteristics that applicable as sensors for controlling environmental pollution like sulfide gas. Thin film of SnO2 as one part of the sulfide gas sensor was synthesized with the chemical liquid deposition method, and characterized by UV/VIS/NIR-Spectrophotometer before and after gas application, also using FTIR, SEM and XRD. Characterization studies showed nanoparticle sizes from the diameters range of 38-71 nm. Application of SnO2 thin film to sulfide gas detected by UV/VIS/NIR Spectrophotometer with diffuse reflectance showed chemical reaction by the shifting of maximum % R peak at wavelength of 1428 cm. The benefit of measurement of sulfide gas using this SnO2 nano thin film is that it could be done at the room temperature.
