The nonradiative transition rates Keep to the formulation WNR = W (0) exp(-alphap), where p is the amount of phonons matching the Vitality gap. The nonradiative changeover charges of Er3+ exhibit temperature dependence according to the multiphonon peace concept. In Tm3+ the temperature dependence of nonradiative relaxation fees is sophisticated via
