The nonradiative changeover premiums Keep to the system WNR = W (0) exp(-alphap), where p is the volume of phonons matching the Strength hole. The nonradiative transition premiums of Er3+ exhibit temperature dependence consistent with the multiphonon rest principle. In Tm3+ the temperature dependence of nonradiative peace charges is complicated https://lobor146pnk6.homewikia.com/user
