The nonradiative transition prices Adhere to the system WNR = W (0) exp(-alphap), where p is the volume of phonons matching the energy gap. The nonradiative changeover charges of Er3+ show temperature dependence consistent with the multiphonon rest concept. In Tm3+ the temperature dependence of nonradiative leisure rates is difficult https://charlesa479xvs0.eedblog.com/profile
