5 SIMPLE STATEMENTS ABOUT ER:YB:YAB CRYSTAL EXPLAINED

The nonradiative transition rates Keep to the components WNR = W (0) exp(-alphap), the place p is the volume of phonons matching the Power gap. The nonradiative changeover charges of Er3+ show temperature dependence according to the multiphonon leisure concept. In Tm3+ the temperature dependence of nonradiative leisure rates is sophisticated via th
