The nonradiative transition rates follow the components WNR = W (0) exp(-alphap), wherever p is the amount of phonons matching the energy gap. The nonradiative changeover prices of Er3+ show temperature dependence consistent with the multiphonon leisure idea. In Tm3+ the temperature dependence of nonradiative relaxation costs is complex through the
