The nonradiative changeover rates Keep to the formulation WNR = W (0) exp(-alphap), where p is the quantity of phonons matching the Electrical power gap. The nonradiative changeover fees of Er3+ exhibit temperature dependence in keeping with the multiphonon peace theory. In Tm3+ the temperature dependence of nonradiative rest costs https://fernandoxywvs.pointblog.net/the-2-minute-rule-for-er-yb-yab-crystal-76352966
