Abstract

Sb₂O₃ and Sb₂O₅ are semiconducting metal oxides which have been used for gas sensing purposes in pristine, decorated, and composite forms. Furthermore, Sb as dopant can be used as substitution element in various metal oxides, where creation of oxygen vacancies and lattice distortion, along with limitation of particle growth causes enhanced gas response. Herein, we have described the various aspects of sensing behavior of resistive sensors based on these materials in detail. Sb₂O₃ with more stability has been more studied for gas sensing application relative to Sb₂O₅. Gas sensing temperature can be decreased to room-temperature using UV illumination or composite making with appropriate semiconducting materials such as conducting polymers. Sb as dopant can increased the conductivity and create oxygen vacancies inside of sensing material, hence increasing sensing performance. Details of sensing mechanism of Sb₂O₃, Sb₂O₅, and Sb-doped sensor are described and mainly related to the formation of Schottky barriers, heterojunctions, oxygen vacancies and increase of surface area.

Sb2O3、Sb2O5和sb掺杂基电阻式气体传感器的研究进展

Sb2O3和Sb2O5是半导体金属氧化物，以原始形式、装饰形式和复合形式用于气敏目的。此外，Sb作为掺杂剂可以在各种金属氧化物中用作取代元素，其中氧空位和晶格畸变的产生以及颗粒生长的限制导致气体响应增强。在此，我们详细描述了基于这些材料的电阻式传感器的传感行为的各个方面。相对于Sb2O5，稳定性更好的Sb2O3在气敏应用方面得到了更多的研究。气敏温度可以降低到室温使用紫外线照明或复合材料与适当的半导体材料，如导电聚合物。Sb作为掺杂剂可以提高传感材料的电导率，并在传感材料内部产生氧空位，从而提高传感性能。详细描述了Sb2O3、Sb2O5和sb掺杂传感器的传感机理，主要与肖特基势垒的形成、异质结、氧空位和表面积的增加有关。
