The nonradiative transition rates follow the formulation WNR = W (0) exp(-alphap), in which p is the amount of phonons matching the Strength hole. The nonradiative transition charges of Er3+ exhibit temperature dependence per the multiphonon relaxation concept. In Tm3+ the temperature dependence of nonradiative relaxation charges is intricate with
