The nonradiative changeover costs Keep to the formulation WNR = W (0) exp(-alphap), the place p is the amount of phonons matching the Electricity hole. The nonradiative transition premiums of Er3+ exhibit temperature dependence consistent with the multiphonon peace idea. In Tm3+ the temperature dependence of nonradiative rest premiums is https://er-yb-yab-crystal30627.webdesign96.com/33654771/5-simple-techniques-for-er-yb-yab-crystal
