The nonradiative changeover rates follow the components WNR = W (0) exp(-alphap), where by p is the volume of phonons matching the Strength hole. The nonradiative transition fees of Er3+ show temperature dependence per the multiphonon relaxation principle. In Tm3+ the temperature dependence of nonradiative peace fees is sophisticated from the exist
