The nonradiative changeover rates Keep to the formula WNR = W (0) exp(-alphap), wherever p is the number of phonons matching the Strength hole. The nonradiative transition costs of Er3+ show temperature dependence consistent with the multiphonon rest principle. In Tm3+ the temperature dependence of nonradiative peace prices is intricate https://jaspernonjg.onesmablog.com/a-secret-weapon-for-er-yb-yab-crystal-73660100
