The nonradiative transition fees follow the formula WNR = W (0) exp(-alphap), where by p is the number of phonons matching the Vitality gap. The nonradiative transition rates of Er3+ exhibit temperature dependence in step with the multiphonon rest theory. In Tm3+ the temperature dependence of nonradiative peace rates is https://chancebyywt.blog-eye.com/33302868/5-simple-statements-about-er-yb-yab-crystal-explained
