The nonradiative transition charges follow the method WNR = W (0) exp(-alphap), the place p is the volume of phonons matching the Electricity gap. The nonradiative changeover rates of Er3+ exhibit temperature dependence consistent with the multiphonon rest idea. In Tm3+ the temperature dependence of nonradiative relaxation costs is complicated https://lukaspvyzy.humor-blog.com/33695618/er-yb-yab-crystal-options
