摘要

ZnO薄膜进行CeO2掺杂

研究掺杂含量和热氧化对薄膜结构、表面、晶粒尺寸及气敏特性的影响。结果显示

用热蒸发制备的高纯Zn膜经500℃热氧化

获得c轴取向ZnO多晶薄膜。掺CeO2可抑制晶粒生长使颗粒细化平均粒径减小

同时改善了ZnO薄膜的体相化学计量比

Zn与O的比例从未掺杂时1∶1.28降到1∶1.191。XPS分析给出薄膜中Zn显+2价

O为-2价。掺CeO2（9%）可大大提高薄膜对乙醇和丙酮的敏感性

灵敏度分别达35和40。

Abstract

The doping effect of CeO2 in thin films structure

topography

grain size and gas sensing properties of ZnO thin films is investigated.The polycrystalline thin films with c-axis orientation can be obtained after thermal vacuum evaporation.The doping behavior can refine the grain size

simultaneously reduce the stoichiometric ratio from Zn∶O=1∶1.28 down to Zn∶O= 1∶1.191.The XPS results show that Zn existed as +2 and O as-2 states.Additionally

CeO2 doping can dramatically enhance the sensitivities to ethanol and acetone

reaching up to 35 and 40

respectively.
