The nonradiative transition premiums Keep to the method WNR = W (0) exp(-alphap), where by p is the quantity of phonons matching the Electrical power hole. The nonradiative changeover charges of Er3+ show temperature dependence in line with the multiphonon rest theory. In Tm3+ the temperature dependence of nonradiative relaxation https://er-yb-yab-crystal41217.ltfblog.com/32292818/a-secret-weapon-for-er-yb-yab-crystal
