The nonradiative transition charges follow the method WNR = W (0) exp(-alphap), the place p is the number of phonons matching the Strength hole. The nonradiative transition prices of Er3+ show temperature dependence consistent with the multiphonon relaxation principle. In Tm3+ the temperature dependence of nonradiative rest charges is complex https://davidi158zbe5.prublogger.com/profile
