The nonradiative changeover fees Keep to the components WNR = W (0) exp(-alphap), where p is the quantity of phonons matching the energy gap. The nonradiative changeover premiums of Er3+ show temperature dependence in step with the multiphonon rest theory. In Tm3+ the temperature dependence of nonradiative rest prices is https://trentonfhgdy.xzblogs.com/74129118/5-essential-elements-for-er-yb-yab-crystal
