论文摘要
讨论了在半导体纳米晶体中发生的一些基本辐射和非辐射过程，并计算了这些过程的速率。特别是，在本综述中，我们探讨了晶体内的过程，例如光子发射，螺旋螺旋体重组，与声子辅助的激子放松，对表面缺陷的捕获，多表面缺陷的产生以及通过nanocrystals组合中的激子迁移而实现的基于晶体的过程。从它们对纳米晶体的光学特性的影响的角度来考虑激发子的过渡，创造和歼灭，并伴随着光子和（或（或）声子发射或吸收。
Some basic radiative and non-radiative processes taking place in semiconductor nanocrystals are discussed, and rates of these processes are calculated. In particular, in the present review we explore both intra-crystallite processes, such as the photon emission, Auger recombination, phonon-assisted exciton relaxation, capture on surface defects, multi-exciton generation, and inter-crystallite processes realized through the exciton migration in ensembles of nanocrystals. Exciton transitions, creation, and annihilation accompanied by the photon and (or) phonon emission or absorption are considered from the point of view of their influence on the optical properties of nanocrystals.
