Abstract

Metal oxide semiconductors have garnered increasing attention in gas sensing applications due to their excellent sensitivity and stability under extreme conditions. In this study, we explore the potential of tin oxide (SnO₂) thin films fabricated via a facile spray coating method to be used as efficient gas sensor devices. Our developed SnO₂-based devices exhibit superior electrical conductivity, strong optical absorption and robust sensing performances. Specifically, the SnO₂ devices show a rapid and linear sensing response towards NO₂ and H₂S sour gases, achieving a high relative sensing response of 13.1, with sensing response and recovery times of 17 s and 5 s, respectively. These findings underscore the SnO₂ thin film capabilities as highly efficient and versatile sensing material for next generation gas sensor technologies.

用于增强硫化氢和二氧化氮传感的可控SnO2纳米结构

金属氧化物半导体由于其在极端条件下优异的灵敏度和稳定性，在气敏应用中受到越来越多的关注。在这项研究中，我们探索了通过简单的喷涂方法制备氧化锡（SnO2）薄膜作为高效气体传感器器件的潜力。我们开发的基于sno2的器件具有优异的导电性，强光吸收和强大的传感性能。具体而言，SnO2器件对NO2和H2S酸性气体具有快速的线性传感响应，实现了较高的相对传感响应13.1，传感响应和恢复时间分别为17 s和5 s。这些发现强调了SnO2薄膜作为下一代气体传感器技术的高效和通用传感材料的能力。
