The nonradiative changeover prices Stick to the method WNR = W (0) exp(-alphap), wherever p is the amount of phonons matching the Electricity gap. The nonradiative changeover rates of Er3+ show temperature dependence consistent with the multiphonon relaxation idea. In Tm3+ the temperature dependence of nonradiative peace prices is complex https://rowanszbzw.idblogmaker.com/32301147/rumored-buzz-on-er-yb-yab-crystal
