The nonradiative transition fees follow the formula WNR = W (0) exp(-alphap), where p is the quantity of phonons matching the energy gap. The nonradiative changeover rates of Er3+ exhibit temperature dependence consistent with the multiphonon rest principle. In Tm3+ the temperature dependence of nonradiative relaxation charges is sophisticated through https://er-yb-yab-crystal29516.humor-blog.com/32288569/a-simple-key-for-er-yb-yab-crystal-unveiled
