The nonradiative transition costs follow the formula WNR = W (0) exp(-alphap), where p is the volume of phonons matching the Strength gap. The nonradiative transition rates of Er3+ exhibit temperature dependence in step with the multiphonon peace theory. In Tm3+ the temperature dependence of nonradiative leisure costs is sophisticated through the e
