The nonradiative changeover rates follow the components WNR = W (0) exp(-alphap), the place p is the number of phonons matching the Strength gap. The nonradiative changeover rates of Er3+ show temperature dependence according to the multiphonon peace idea. In Tm3+ the temperature dependence of nonradiative relaxation fees is difficult through the e
