The nonradiative transition rates Keep to the method WNR = W (0) exp(-alphap), exactly where p is the quantity of phonons matching the Power gap. The nonradiative transition charges of Er3+ exhibit temperature dependence according to the multiphonon rest principle. In Tm3+ the temperature dependence of nonradiative leisure costs is https://cruzhxlxj.blogadvize.com/42402175/the-5-second-trick-for-er-yb-yab-crystal
