5 SIMPLE STATEMENTS ABOUT ER:YB:YAB CRYSTAL EXPLAINED

The nonradiative changeover fees follow the formula WNR = W (0) exp(-alphap), wherever p is the quantity of phonons matching the Strength gap. The nonradiative changeover charges of Er3+ show temperature dependence in line with the multiphonon rest theory. In Tm3+ the temperature dependence of nonradiative peace charges is challenging via the exist
