The Definitive Guide to Er:Yb:YAB Crystal
The nonradiative transition premiums follow the system WNR = W (0) exp(-alphap), the place p is the number 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 relaxation costs is difficult
