5 SIMPLE STATEMENTS ABOUT ER:YB:YAB CRYSTAL EXPLAINED

The nonradiative changeover charges follow the components WNR = W (0) exp(-alphap), where p is the quantity of phonons matching the Vitality gap. The nonradiative changeover rates of Er3+ show temperature dependence in keeping with the multiphonon leisure principle. In Tm3+ the temperature dependence of nonradiative relaxation premiums is difficult
