The nonradiative changeover fees Adhere to the components WNR = W (0) exp(-alphap), where p is the amount of phonons matching the Vitality hole. The nonradiative changeover rates of Er3+ show temperature dependence in step with the multiphonon peace theory. In Tm3+ the temperature dependence of nonradiative rest rates is https://er-yb-yab-crystal40639.collectblogs.com/78092491/the-5-second-trick-for-er-yb-yab-crystal
