The nonradiative transition fees follow the formulation WNR = W (0) exp(-alphap), where by p is the number of phonons matching the Vitality gap. The nonradiative changeover costs of Er3+ exhibit temperature dependence per the multiphonon rest theory. In Tm3+ the temperature dependence of nonradiative peace fees is complicated by the existence of se
