论文编号:WLX076 字数:8253,页数:20摘要 光通过固体时，与固体中存在的电子、激子、晶格振动以及杂质和缺陷等发生相互作用，使光通过固体后强度相应的减少，这就是光吸收的微观作用机理。研究固体中的光吸收可以直接的获得固体中有关电子状态，能级结构以及其他各种激发态的信息，是研究固体性质的一个重要参量。本文通过光学材料的光学常数及其关系，半导体材料的本征吸收和磁回旋共振吸收以及离子晶体的长光学波红外吸收的特征来研究固体中光吸收特点，然后具体分析实际的产品。关键词：光吸收 光学常数 磁回旋吸收 红外吸收Abstract When pass through the solid, the optical interact with the electronic , Exciton, impurities and lattice defects, vibration exist in the solid. So its strength will be reduced more or less. This is the microscopic mechanism of optical absorption. Absorption of light by solids can be directly related to the acquisition of solid state electronics, Energy level structure and excited states of other information, is an important parameter to study the nature of Solid. In this paper, By analyzing the optical constants of optical materials and their relationship, the intrinsic absorption of semiconductor materials and magnetic, and ion cyclotron resonance absorption of the long lens features optical wave infrared absorption to study the process of light absorption in solids and its characteristics, And specific analysis of the actual product..Key Words: Optical absorption ; Optical constants ;Magnetic cyclotron absorption ;Infrared absorption 目 录中文摘要 1英文摘要 2目录 3第一章 绪论 41.1 研究动机与目的 41.2 研究背景 41.3 研究方法与系统描述 5第二章 固体光吸收特征分析 62.1 光学常数及其关系和测量 62.1.1 折射率和消光系数...............................................62.1.2 介电常量和电导率 62.1.3 穿透深度.......................................................72.1.4 反射率和折射率.................................................72.1.5 Kramers-Kronig关系.............................................82.1.6 Kramers-Kronig公式............................................82.1.7 透明薄膜光学常数测定...........................................82.1.8 非均匀薄膜光学常数测定.........................................9 2.2 本征吸收及磁回旋共振吸收.............................................9 2.2.1 本征吸收过程..................................................10 2.2.2 磁回旋共振吸收................................................13 2.3 离子晶体的红外吸收...................................................13 2.3.1 红外吸收的原理................................................13 2.3.2 模型讨论......................................................14第三章 固体中光吸收应用 15第四章 结论 18致谢 19参考文献 20 |
