The nonradiative transition rates follow the components WNR = W (0) exp(-alphap), exactly where p is the volume of phonons matching the energy hole. The nonradiative changeover rates of Er3+ show temperature dependence in step with the multiphonon peace idea. In Tm3+ the temperature dependence of nonradiative leisure fees is https://englandm914iif4.thecomputerwiki.com/user
