5 SIMPLE TECHNIQUES FOR ER:YB:YAB CRYSTAL

The nonradiative transition rates Stick to the formula WNR = W (0) exp(-alphap), exactly where p is the volume of phonons matching the Strength hole. The nonradiative changeover prices of Er3+ exhibit temperature dependence consistent with the multiphonon rest concept. In Tm3+ the temperature dependence of nonradiative leisure premiums is complex w
