The nonradiative changeover fees Keep to the components WNR = W (0) exp(-alphap), where by p is the number of phonons matching the Strength hole. The nonradiative changeover costs of Er3+ exhibit temperature dependence per the multiphonon rest principle. In Tm3+ the temperature dependence of nonradiative rest prices is intricate https://er-yb-yab-crystal86317.dailyblogzz.com/33680205/getting-my-er-yb-yab-crystal-to-work
