The nonradiative transition costs follow the method WNR = W (0) exp(-alphap), exactly where p is the quantity of phonons matching the energy gap. The nonradiative changeover rates of Er3+ exhibit temperature dependence in keeping with the multiphonon peace theory. In Tm3+ the temperature dependence of nonradiative rest premiums is https://titusoqdhi.blogars.com/32076885/details-fiction-and-er-yb-yab-crystal
