The nonradiative changeover rates Adhere to the components WNR = W (0) exp(-alphap), where by p is the amount of phonons matching the Electrical power gap. The nonradiative changeover rates of Er3+ exhibit temperature dependence in keeping with the multiphonon peace theory. In Tm3+ the temperature dependence of nonradiative relaxation https://er-yb-yab-crystal30517.myparisblog.com/33706226/the-ultimate-guide-to-er-yb-yab-crystal
