The nonradiative transition costs follow the formulation WNR = W (0) exp(-alphap), exactly where p is the quantity of phonons matching the Vitality hole. The nonradiative changeover prices of Er3+ exhibit temperature dependence consistent with the multiphonon rest principle. In Tm3+ the temperature dependence of nonradiative leisure premiums is challenging https://waylonzobcb.blogpayz.com/34887411/the-2-minute-rule-for-er-yb-yab-crystal
