The nonradiative transition charges follow the method WNR = W (0) exp(-alphap), where p is the quantity of phonons matching the energy gap. The nonradiative changeover rates of Er3+ exhibit temperature dependence in keeping with the multiphonon relaxation theory. In Tm3+ the temperature dependence of nonradiative rest premiums is complex https://er-yb-yab-crystal02484.boyblogguide.com/33781173/5-simple-statements-about-er-yb-yab-crystal-explained
