The nonradiative changeover prices follow the system WNR = W (0) exp(-alphap), exactly where p is the volume of phonons matching the Strength hole. The nonradiative transition costs of Er3+ show temperature dependence in step with the multiphonon leisure idea. In Tm3+ the temperature dependence of nonradiative leisure fees is difficult because of t
