The nonradiative changeover prices Adhere to the method 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 according to the multiphonon rest principle. In Tm3+ the temperature dependence of nonradiative relaxation charges is sophisticated https://er-yb-yab-crystal30517.myparisblog.com/33706226/the-ultimate-guide-to-er-yb-yab-crystal
