The nonradiative transition costs Keep to the formulation WNR = W (0) exp(-alphap), wherever p is the volume of phonons matching the energy hole. The nonradiative transition rates of Er3+ show temperature dependence per the multiphonon relaxation theory. In Tm3+ the temperature dependence of nonradiative rest premiums is complicated through the exi
