摘要

采用溶胶凝胶法制备Eu2O3-Fe2O3（Eu2O3的质量分数为0

%）纳米粉体材料

利用X射线衍射仪、透射电镜等测试手段分析了材料的微观结构

并进行了气敏性能测试。结果表明:合成的产物颗粒均匀、粒径细小。其中

质量分数为5%Eu2O3的烧结型气敏元件在145℃条件下对H2S有较高的灵敏度、较好的选择性及响应恢复特性

线性检测范围较宽

有望研制成气敏性能较为优异的H2S敏感材料。

Abstract

The nanocrystals of Eu-doping α-Fe

（quality fraction of Eu

is 0

%） are prepared by sol-gel method in the citric acid system.By means of XRD and TEM

microstructure is analyzed.The gas-sensing properties of sensors are also measured.Obtained results show that the grain size becomes reqular and smaller

the sensor has high sensitivity

good selectivity

response-recovery characteristic and wide linear measurment range to H

S when quality fraction of Eu

is 5 % and optimum working temperature is（145 ℃）.It is hopeful of developing into a new type of H

S sensing material.
