The nonradiative transition charges Stick to the formulation WNR = W (0) exp(-alphap), in which p is the quantity of phonons matching the Power gap. The nonradiative changeover rates of Er3+ exhibit temperature dependence in keeping with the multiphonon relaxation idea. In Tm3+ the temperature dependence of nonradiative relaxation costs https://erybyabcrystal96283.jaiblogs.com/60126931/er-yb-yab-crystal-an-overview
