The nonradiative changeover rates follow the formula WNR = W (0) exp(-alphap), exactly where p is the volume of phonons matching the Electricity gap. The nonradiative transition premiums of Er3+ show temperature dependence in step with the multiphonon relaxation concept. In Tm3+ the temperature dependence of nonradiative peace charges is https://er-yb-yab-crystal42854.ambien-blog.com/39580017/5-essential-elements-for-er-yb-yab-crystal
