The nonradiative transition rates Adhere to the formulation WNR = W (0) exp(-alphap), the place p is the number of phonons matching the Strength hole. The nonradiative transition charges of Er3+ show temperature dependence in line with the multiphonon leisure idea. In Tm3+ the temperature dependence of nonradiative relaxation costs https://riverhoomk.idblogz.com/33640180/the-5-second-trick-for-er-yb-yab-crystal
