Abstract

Semiconductor materials based on SnO₂ with different contents of cerium and stibium have been obtained. Their phase compositions, particle sizes and sensitivities of semiconductor sensors based on them to hydrogen have been studied. It is found that introduction of cerium into the material contributes to reduce the sizes of SnO₂ nanoparticles. Changes in the values of the sensor responses to hydrogen are explained by influence of catalytic activity of cerium and the competing effect of the introduced stibium on conductivities of the materials.

铈和锑添加剂对纳米SnO2半导体传感器对氢灵敏度的影响

制备了不同铈、锑含量的SnO2基半导体材料。研究了它们的相组成、粒径和基于它们的半导体传感器对氢的灵敏度。研究发现，在材料中引入铈有助于减小SnO2纳米颗粒的尺寸。传感器对氢响应值的变化可以用铈的催化活性的影响和引入的锑对材料电导率的竞争效应来解释。
