摘要

本文采用溶剂热法设计了掺杂sm的In2O3纳米颗粒。该材料首次用于正丁醇气体的检测。通过表征和测试材料的性能，研究了材料的气敏性能。与原始In2O3纳米材料相比，sm掺杂的In2O3纳米材料在250℃下表现出更好的正丁醇传感性能。特别是，掺杂6 mol% Sm的In2O3纳米材料的传感器在50 ppm正丁醇下的响应值高达70，是原始In2O3的2.6倍。此外，该材料制成的传感器具有良好的稳定性和快速的响应时间为4 s。结果表明，Sm掺杂提高了In2O3传感器的气敏性能，并对其气敏性能提高的原因进行了详细的分析。

Highly Sensitive n-Butanol Gas Sensor Based on Sm-Doped In₂O₃

In this paper, Sm-doped In₂O₃ nanoparticles were designed by a solvothermal method. This material was reported for the detection of n-butanol gas for the first time. By characterizing and testing the properties of the materials, we researched the gas-sensitive properties of the materials. In comparison with the pristine In₂O₃ nanomaterials, the Sm-doped In₂O₃ nanomaterials exhibited better n-butanol sensing performance at 250 ℃. In particular, sensors made of In₂O₃ nanomaterials doped with 6 mol% Sm showed a response value up to 70 for 50 ppm n-butanol, which is 2.6 times that of the pristine In₂O₃. Furthermore, the sensors made of this material have good stability and fast response time of 4 s. It is shown that Sm doping enhances the gas-sensing properties of the In₂O₃ sensor, and the reasons for the improved gas sensitivity are explained in detail in this study.
