The nonradiative transition rates Adhere to the formulation WNR = W (0) exp(-alphap), in which p is the number of phonons matching the Electrical power gap. The nonradiative changeover charges of Er3+ show temperature dependence in line with the multiphonon leisure idea. In Tm3+ the temperature dependence of nonradiative relaxation https://brooksbdbzv.activosblog.com/32172895/er-yb-yab-crystal-can-be-fun-for-anyone
