5 SIMPLE STATEMENTS ABOUT ER:YB:YAB CRYSTAL EXPLAINED

The nonradiative transition fees Keep to the formula WNR = W (0) exp(-alphap), where by p is the number of phonons matching the Power hole. The nonradiative changeover costs of Er3+ exhibit temperature dependence in step with the multiphonon rest concept. In Tm3+ the temperature dependence of nonradiative relaxation charges is sophisticated via the
