The nonradiative changeover charges Keep to the method WNR = W (0) exp(-alphap), where by p is the amount of phonons matching the Vitality gap. The nonradiative transition charges of Er3+ show temperature dependence consistent with the multiphonon relaxation principle. In Tm3+ the temperature dependence of nonradiative rest prices is https://er-yb-yab-crystal59360.mdkblog.com/38916910/top-latest-five-er-yb-yab-crystal-urban-news
