The nonradiative transition rates 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 consistent with the multiphonon leisure theory. In Tm3+ the temperature dependence of nonradiative relaxation rates is https://er-yb-yab-crystal41728.blogdon.net/5-simple-statements-about-er-yb-yab-crystal-explained-49246839
