The nonradiative changeover costs follow the system WNR = W (0) exp(-alphap), exactly where p is the quantity of phonons matching the energy gap. The nonradiative changeover rates of Er3+ exhibit temperature dependence according to the multiphonon peace concept. In Tm3+ the temperature dependence of nonradiative leisure rates is intricate https://reidpuvjk.blogrelation.com/41051232/a-secret-weapon-for-er-yb-yab-crystal
