Generally, there are two paths for the excited ions relax to the ground state: (1) radiative process with emission of photons, (2) non-radiative process. The lifetime t can be written as: t=1/(Rr+Rnr) where Rr is the decay rate of radiative process, and Rnr is the rate of non-radiative process. tÊÇÓ«¹âÊÙÃü 1/RrÊÇ·øÉäÊÙÃü£¿ »òÕßÁ½Õß¶¼ÊÇt¡£ |
