The nonradiative changeover prices Adhere to the formulation WNR = W (0) exp(-alphap), wherever p is the volume of phonons matching the Strength hole. The nonradiative transition rates of Er3+ exhibit temperature dependence consistent with the multiphonon relaxation theory. In Tm3+ the temperature dependence of nonradiative rest fees is complicated https://troylmjgd.ambien-blog.com/39676246/5-simple-statements-about-er-yb-yab-crystal-explained
