The nonradiative changeover costs Stick to the system WNR = W (0) exp(-alphap), exactly where p is the amount of phonons matching the Strength gap. The nonradiative changeover premiums of Er3+ exhibit temperature dependence per the multiphonon peace theory. In Tm3+ the temperature dependence of nonradiative leisure costs is difficult https://beckettuwvto.aboutyoublog.com/36337625/the-definitive-guide-to-er-yb-yab-crystal
