5 SIMPLE STATEMENTS ABOUT ER:YB:YAB CRYSTAL EXPLAINED

The nonradiative transition fees Stick to the formulation WNR = W (0) exp(-alphap), exactly where p is the number of phonons matching the energy gap. The nonradiative changeover costs of Er3+ exhibit temperature dependence according to the multiphonon rest principle. In Tm3+ the temperature dependence of nonradiative relaxation costs is complex bec
