The nonradiative changeover rates Adhere to the formulation WNR = W (0) exp(-alphap), in which p is the quantity of phonons matching the energy gap. The nonradiative transition prices of Er3+ exhibit temperature dependence consistent with the multiphonon rest idea. In Tm3+ the temperature dependence of nonradiative rest charges is https://er-yb-yab-crystal52951.bloguerosa.com/32321436/er-yb-yab-crystal-an-overview
