The nonradiative changeover charges Keep to the components WNR = W (0) exp(-alphap), exactly where p is the volume of phonons matching the Strength hole. The nonradiative changeover prices of Er3+ show temperature dependence per the multiphonon rest theory. In Tm3+ the temperature dependence of nonradiative relaxation prices is complex https://andrewd680zwt9.mappywiki.com/user
