The nonradiative transition costs follow the system WNR = W (0) exp(-alphap), exactly where p is the volume of phonons matching the Vitality gap. The nonradiative changeover prices of Er3+ exhibit temperature dependence in keeping with the multiphonon relaxation concept. In Tm3+ the temperature dependence of nonradiative relaxation charges is https://rowanfjigd.buyoutblog.com/33156546/rumored-buzz-on-er-yb-yab-crystal
