The nonradiative changeover rates Keep to the formula WNR = W (0) exp(-alphap), wherever p is the number of phonons matching the Electricity gap. The nonradiative changeover prices of Er3+ exhibit temperature dependence according to the multiphonon rest theory. In Tm3+ the temperature dependence of nonradiative leisure rates is challenging https://er-yb-yab-crystal30517.blogoscience.com/39407893/getting-my-er-yb-yab-crystal-to-work
