摘要
采用水热法与酸处理相结合方法合成具有氧缺陷的立方结构ZnSnO3,利用X射线衍射(XRD)、电子扫描电镜(FE-SEM)、透射电镜(TEM)分析了材料的形貌与结构.将立方ZnSnO3材料制作成传感器,对其进行了气敏性能测试,发现ZnSnO3对H2S气体展现出卓越的敏感特性.通过光致发光(PL)分析材料氧缺陷特征,给出了敏感材料可能的气敏机理.
The cubic structure ZnSnO3 with oxygen vacancies was synthesized by the hydrothermal combined with acid treatment method.The morphology and structure of the materials were analyzed by X-ray diffraction(XRD),electron scanning electron microscopy(FE-SEM)and transmission electron microscopy(TEM).The resistance-type sensor with the cubic ZnSnO3 as sensing material was fabricated.The sensor exhibited high sensing performance for H2S.The oxygen vacancy was confirmed by photoluminescence(PL),and the possible gas-sensitive mechanism was discussed.
