The nonradiative changeover rates follow the formulation WNR = W (0) exp(-alphap), exactly where p is the number of phonons matching the Power gap. The nonradiative transition fees of Er3+ exhibit temperature dependence in keeping with the multiphonon leisure concept. In Tm3+ the temperature dependence of nonradiative peace charges is https://er-yb-yab-crystal42962.mdkblog.com/38884093/getting-my-er-yb-yab-crystal-to-work
