The nonradiative changeover charges follow the formulation WNR = W (0) exp(-alphap), exactly where p is the volume of phonons matching the Electricity hole. The nonradiative changeover prices of Er3+ exhibit temperature dependence according to the multiphonon peace theory. In Tm3+ the temperature dependence of nonradiative rest premiums is complicated https://beckettuwvto.aboutyoublog.com/36337625/the-definitive-guide-to-er-yb-yab-crystal
