The nonradiative changeover charges Keep to the method WNR = W (0) exp(-alphap), the place p is the number of phonons matching the Strength hole. The nonradiative transition rates of Er3+ exhibit temperature dependence in line with the multiphonon rest idea. In Tm3+ the temperature dependence of nonradiative rest fees https://erybyabcrystal84062.bloggerswise.com/40384738/the-best-side-of-er-yb-yab-crystal
