The nonradiative transition rates Keep to the formulation WNR = W (0) exp(-alphap), where p is the quantity of phonons matching the energy gap. The nonradiative changeover premiums of Er3+ exhibit temperature dependence per the multiphonon peace theory. In Tm3+ the temperature dependence of nonradiative rest fees is difficult because https://israelttyih.blogsmine.com/33628125/top-latest-five-er-yb-yab-crystal-urban-news
