摘要

对In2O3粉体进行Fe掺杂

采用水热法合成了In2O3粉体。通过X射线衍射（XRD）

扫描电镜（SEM）

透射电子显微镜（TEM）等手段对粉体的物相、形貌、粒度等进行表征。TEM图表明:质量分数为7%Fe掺杂的样品为均匀排列的棒

长度约为300～500 nm

宽度约20 nm。对样品进行气敏性能研究

结果表明:质量分数为7%Fe掺杂的In2O3气敏元件

当工作温度为125℃时

对100×10-6Cl2的灵敏度高达182.75。元件对10×10-6Cl2的灵敏度为17.9

可以检测到低体积分数的Cl2。并具有选择性好、响应-恢复时间短等特性。

Abstract

The preparation of Fe doped In2O3 nano-powder using a hydrothermal method is introduced.Its size

phase and morphology are analyzed by XRD

SEM and TEM.The gas sensing characteristics of the materials are tested in static slate.The results show that the morphology of the In2O3 with mass fraction 7% Fe is rods with good dispersity.The average length of the as-synthesized rods is about 300～500nm

and the width is 20 nm.The In2O3 with mass fraction 7% Fe has the highest sensitivity as high as 182.75 to 100×10-6 Cl2 at lower working temperature 125℃.And the In2O3 with mass fraction 7% Fe also has a high sensitivity as high as 17.9 to 10×10-6 Cl2 at 125℃.So the sensors can tests low volume fraction of Cl2.The sensor based on In2O3 also has satisfied selectivity

quick response and recover.
