5 SIMPLE STATEMENTS ABOUT ER:YB:YAB CRYSTAL EXPLAINED

The nonradiative transition costs follow the system WNR = W (0) exp(-alphap), wherever p is the quantity of phonons matching the Vitality gap. The nonradiative changeover costs of Er3+ show temperature dependence according to the multiphonon leisure idea. In Tm3+ the temperature dependence of nonradiative leisure costs is complex by the existence o
