The nonradiative changeover rates Keep to the formulation WNR = W (0) exp(-alphap), where p is the number of phonons matching the Strength hole. The nonradiative transition charges of Er3+ show temperature dependence in line with the multiphonon rest principle. In Tm3+ the temperature dependence of nonradiative peace rates is difficult via the exis
