The nonradiative transition rates Adhere to the formula WNR = W (0) exp(-alphap), wherever p is the amount of phonons matching the Vitality gap. The nonradiative changeover costs of Er3+ show temperature dependence per the multiphonon rest concept. In Tm3+ the temperature dependence of nonradiative peace prices is complex via https://sethjlkhu.csublogs.com/39994460/top-guidelines-of-er-yb-yab-crystal
