5 SIMPLE STATEMENTS ABOUT ER:YB:YAB CRYSTAL EXPLAINED

The nonradiative transition rates Adhere to the formulation WNR = W (0) exp(-alphap), the place p is the number of phonons matching the Vitality hole. The nonradiative changeover costs of Er3+ exhibit temperature dependence in line with the multiphonon leisure idea. In Tm3+ the temperature dependence of nonradiative rest costs is complex because of
