The nonradiative changeover premiums follow the method WNR = W (0) exp(-alphap), exactly where p is the quantity of phonons matching the Electrical power gap. The nonradiative transition rates of Er3+ exhibit temperature dependence in step with the multiphonon rest concept. In Tm3+ the temperature dependence of nonradiative rest charges https://er-yb-yab-crystal22849.link4blogs.com/54519270/er-yb-yab-crystal-can-be-fun-for-anyone
