The nonradiative transition costs Keep to the formula WNR = W (0) exp(-alphap), where p is the number of phonons matching the energy hole. The nonradiative transition premiums of Er3+ show temperature dependence per the multiphonon leisure principle. In Tm3+ the temperature dependence of nonradiative relaxation costs is difficult via the existence
