The nonradiative transition costs Stick to the method WNR = W (0) exp(-alphap), the place p is the volume of phonons matching the Power gap. The nonradiative changeover costs of Er3+ show temperature dependence consistent with the multiphonon rest idea. In Tm3+ the temperature dependence of nonradiative rest premiums is https://horaceh036hif4.life-wiki.com/user
