The nonradiative changeover rates Keep to the formula WNR = W (0) exp(-alphap), in which p is the quantity of phonons matching the Power gap. The nonradiative changeover costs of Er3+ exhibit temperature dependence in line with the multiphonon relaxation concept. In Tm3+ the temperature dependence of nonradiative relaxation fees https://cashfqyzq.blogsmine.com/33643231/a-secret-weapon-for-er-yb-yab-crystal
