The nonradiative transition costs follow the formula WNR = W (0) exp(-alphap), where by p is the volume of phonons matching the Electricity gap. The nonradiative changeover fees of Er3+ exhibit temperature dependence according to the multiphonon rest principle. In Tm3+ the temperature dependence of nonradiative relaxation rates is intricate https://er-yb-yab-crystal30516.ja-blog.com/33377427/the-ultimate-guide-to-er-yb-yab-crystal
