The nonradiative changeover premiums follow the formulation WNR = W (0) exp(-alphap), the place p is the amount of phonons matching the Vitality gap. The nonradiative changeover rates of Er3+ exhibit temperature dependence in step with the multiphonon peace principle. In Tm3+ the temperature dependence of nonradiative leisure premiums is https://erybyabcrystal18416.blogerus.com/55431063/er-yb-yab-crystal-an-overview
