从全光通信对光子器件的要求出发 ,报道了近年来在半导体 /介质纳米颗粒镶嵌材料中光致载流子弛豫过程的研究进展。强量子限制效应可以大大地减小激子的寿命 ,但这种材料 ( - 族例外 )普遍存在着长寿命的俘获态 ,制约着这种材料的光学响应速度的提高 Proceeding from the requirements of all-optical communication for photonic devices, the research progress of photocharge carrier relaxation in semiconductor / dielectric nanoparticle damascene materials has been reported in recent years. The strong quantum confinement effect can greatly reduce the lifetime of excitons, but the long-lived trapped states of this material (exception of the family) prevail, which limits the optical response speed of this material
