The nonradiative transition charges follow the formulation WNR = W (0) exp(-alphap), in which p is the amount of phonons matching the Vitality gap. The nonradiative changeover rates of Er3+ show temperature dependence in step with the multiphonon leisure idea. In Tm3+ the temperature dependence of nonradiative rest charges is https://augustmnljf.blogozz.com/32414745/helping-the-others-realize-the-advantages-of-er-yb-yab-crystal
