Mn^(4+)离子光谱学基础

Basic Knowledge for Understanding Spectroscopic Property of Mn^(4+)Ion

介绍了Mn^(4+)离子发光光谱学的一些基础知识,包括如何确定Mn^(4+)自由离子的光谱项和如何确定Mn^(4+)离子各光谱项在八面体晶体场中的劈裂等。最后就如何理解Mn^(4+)激活荧光粉的荧光光谱(比如如何确定各跃迁的零声子线位置、如何调节发射光子能量等)进行了讨论。

By introducing the related basic knowledge,this paper provided a tutorial for understand-ing the optical property of Mn^(4+)ion,including how to determine the LS term of a free Mn^(4+)ion,and how to determine the splitting of these LS terms in an Oh point group,etc.Finally,this paper dis-cussed how to analyze the photoluminescence spectra of Mn^(4+)-doped phosphors,including how to de-termine the zero phonon line energy of each involved transitions,how to adjust the energy of the emitting photons,etc.
