The nonradiative changeover costs Adhere to the formula WNR = W (0) exp(-alphap), where by p is the amount of phonons matching the energy hole. The nonradiative changeover charges of Er3+ exhibit temperature dependence according to the multiphonon rest principle. In Tm3+ the temperature dependence of nonradiative relaxation prices is https://jeffreyjzlxi.therainblog.com/33655223/the-2-minute-rule-for-er-yb-yab-crystal
