The nonradiative changeover prices Adhere to the method WNR = W (0) exp(-alphap), exactly where p is the volume of phonons matching the energy hole. The nonradiative changeover charges of Er3+ show temperature dependence consistent with the multiphonon rest principle. In Tm3+ the temperature dependence of nonradiative peace rates is https://chancehjheb.blogdal.com/33584989/examine-this-report-on-er-yb-yab-crystal
