The nonradiative transition rates Keep to the formula WNR = W (0) exp(-alphap), the place p is the volume of phonons matching the Vitality hole. The nonradiative changeover charges of Er3+ exhibit temperature dependence consistent with the multiphonon leisure idea. In Tm3+ the temperature dependence of nonradiative relaxation charges is https://er-yb-yab-crystal74184.blogrenanda.com/41173333/the-definitive-guide-to-er-yb-yab-crystal
