The nonradiative changeover rates Adhere to the formulation WNR = W (0) exp(-alphap), where p is the quantity of phonons matching the energy hole. The nonradiative changeover rates of Er3+ exhibit temperature dependence according to the multiphonon relaxation principle. In Tm3+ the temperature dependence of nonradiative peace rates is challenging https://er-yb-yab-crystal53063.ambien-blog.com/41275058/rumored-buzz-on-er-yb-yab-crystal
