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://cashfqyzq.blogsmine.com/33643231/a-secret-weapon-for-er-yb-yab-crystal
