The nonradiative transition rates Keep to the method WNR = W (0) exp(-alphap), where by p is the volume of phonons matching the Power hole. The nonradiative transition charges of Er3+ exhibit temperature dependence per the multiphonon relaxation principle. In Tm3+ the temperature dependence of nonradiative leisure charges is sophisticated https://er-yb-yab-crystal41728.blogdun.com/33922274/a-secret-weapon-for-er-yb-yab-crystal
