The nonradiative changeover rates follow the system WNR = W (0) exp(-alphap), the place p is the quantity of phonons matching the Electricity hole. The nonradiative changeover rates of Er3+ exhibit temperature dependence in step with the multiphonon peace principle. In Tm3+ the temperature dependence of nonradiative rest prices is https://er-yb-yab-crystal30741.xzblogs.com/74008605/top-guidelines-of-er-yb-yab-crystal
