The nonradiative changeover rates follow the formula WNR = W (0) exp(-alphap), where p is the amount of phonons matching the Electricity hole. The nonradiative changeover costs of Er3+ exhibit temperature dependence according to the multiphonon leisure idea. In Tm3+ the temperature dependence of nonradiative relaxation charges is challenging via https://er-yb-yab-crystal75207.ambien-blog.com/41298083/what-does-er-yb-yab-crystal-mean
