The nonradiative changeover fees Keep to the formula WNR = W (0) exp(-alphap), where by p is the amount of phonons matching the Electricity hole. The nonradiative changeover rates of Er3+ exhibit temperature dependence consistent with the multiphonon peace theory. In Tm3+ the temperature dependence of nonradiative rest fees is https://fernandoybpbm.get-blogging.com/35348215/the-2-minute-rule-for-er-yb-yab-crystal
