THE GREATEST GUIDE TO ER:YB:YAB CRYSTAL

The nonradiative transition premiums follow the formulation WNR = W (0) exp(-alphap), wherever p is the volume of phonons matching the energy gap. The nonradiative changeover rates of Er3+ show temperature dependence consistent with the multiphonon relaxation theory. In Tm3+ the temperature dependence of nonradiative peace fees is complex from the
