The nonradiative changeover rates Stick to the method WNR = W (0) exp(-alphap), in which p is the number of phonons matching the Power hole. The nonradiative transition rates of Er3+ exhibit temperature dependence in step with the multiphonon relaxation theory. In Tm3+ the temperature dependence of nonradiative peace charges https://er-yb-yab-crystal48158.getblogs.net/65658764/er-yb-yab-crystal-an-overview
