The nonradiative changeover premiums Stick to the components WNR = W (0) exp(-alphap), in which p is the quantity of phonons matching the energy hole. The nonradiative transition rates of Er3+ show temperature dependence according to the multiphonon rest principle. In Tm3+ the temperature dependence of nonradiative relaxation premiums is challengin
