The nonradiative transition costs follow the formula WNR = W (0) exp(-alphap), where by p is the quantity of phonons matching the Power hole. The nonradiative changeover charges of Er3+ exhibit temperature dependence in step with the multiphonon leisure principle. In Tm3+ the temperature dependence of nonradiative relaxation charges is https://waylonvvtzv.yomoblog.com/39694537/examine-this-report-on-er-yb-yab-crystal
