The nonradiative changeover rates follow the formulation WNR = W (0) exp(-alphap), the place p is the amount of phonons matching the Electrical power hole. The nonradiative transition fees of Er3+ exhibit temperature dependence in step with the multiphonon relaxation principle. In Tm3+ the temperature dependence of nonradiative rest fees https://er-yb-yab-crystal63950.blogvivi.com/33698417/er-yb-yab-crystal-an-overview
