文档介绍：氧化钒材料在红外探测器中的应用 2012 年 10月 1 摘要由于红外辐射是人眼不可见的,要察觉其存在,测量其强弱,就必须首先利用红外探测器将其转换为某种便于测量的信号。红外探测器是红外探测或成像系统中的核心器件,也是红外技术发展最活跃的领域。红外技术的发展水平,通常是以红外探测器的发展水平为主要标志的。氧化钒作为一种被普遍看好的探测器材料成为各国研究的热点。本文主要介绍了二氧化钒和五氧化二钒的结构、二氧化钒相变原理并从相变晶体学和相变时的能带变化的角度介绍了相变特征,对影响相变的因素也进行了一定的分析。随后介绍了氧化钒材料在红外探测中的应用,其中重点介绍了氧化钒热敏薄膜研究以及微测辐射热计红外探测器。关键词: 氧化钒,相变原理,红外探测器 2 Abstract Infrared radiation is not visible to people ’s eyes, so we must use the infrared detector to convert it toa convenient measurement signal when detecting its existence or measuring its strength. Infrared detector is the core device of infrared detection or imaging system, and it is also the most active field of the development of infrared technology. The level of development of infrared technology, usually represented by the level of infrared detector ’s development. Vanadium oxide has been a research focus of all countries asa very good detector ’s material. This paper mainly introduces the structure of VO 2 and V 2O 5, phase transition principle of VO 2 and its transformation characteristics from the perspectives of crystallography and band changes when phase changed, then we analysis the factors which influence phase change. Finally, the paper introduces the appli ance of vanadium oxide in infrared detection, mainly focusing on the research of thin film of vanadium oxide as well as the micro bolometer IR detector. . Key words: Vanadium oxide , Principle of phase transformation , Infrared detector 3 目录摘要.......................................................................................................... 1 Abstract ........................................................................................................ 2 目录.......................................................................................................... 3 绪论.......................................................................................................... 4 1 氧化钒的结构.......................................................................................
