The nonradiative changeover costs Keep to the components WNR = W (0) exp(-alphap), where p is the volume of phonons matching the Electrical power gap. The nonradiative transition fees of Er3+ show temperature dependence consistent with the multiphonon rest theory. In Tm3+ the temperature dependence of nonradiative peace prices is https://eugenev480eha5.idblogz.com/profile
