The nonradiative transition costs Keep to the formulation WNR = W (0) exp(-alphap), the place p is the number of phonons matching the energy gap. The nonradiative transition rates of Er3+ exhibit temperature dependence in line with the multiphonon leisure theory. In Tm3+ the temperature dependence of nonradiative rest fees https://er-yb-yab-crystal52739.blogkoo.com/considerations-to-know-about-er-yb-yab-crystal-52634932
