纳米微粒的光学性质是固体微结构、微器件研究中的重要方向。纳米微粒可用于光信息存储、转换及光开关等,影响其光学性质的因素有尺寸、结构、组成及其周围的化学环境等。在结构和成分不变时微粒的光学吸收带边(E_g)可由下式描述:
The optical properties of nano-particles are solid micro-structure, micro-devices in the study of the important direction. Nanoparticles can be used for optical information storage, conversion and optical switches, etc., affecting the optical properties of factors such as size, structure, composition and the surrounding chemical environment. The optical absorption edge (E_g) of a particle at the same structure and composition can be described by the following equation:
