The nonradiative changeover rates Adhere to the formulation WNR = W (0) exp(-alphap), where p is the quantity of phonons matching the energy gap. The nonradiative changeover prices of Er3+ exhibit temperature dependence consistent with the multiphonon peace idea. In Tm3+ the temperature dependence of nonradiative relaxation costs is complicated https://lorenzosxvxy.total-blog.com/er-yb-yab-crystal-an-overview-58390156
