The nonradiative changeover prices Keep to the formulation WNR = W (0) exp(-alphap), where p is the volume of phonons matching the energy hole. The nonradiative changeover costs of Er3+ exhibit temperature dependence per the multiphonon rest idea. In Tm3+ the temperature dependence of nonradiative rest prices is challenging by https://er-yb-yab-crystal86396.blogunteer.com/33767142/er-yb-yab-crystal-an-overview
