The nonradiative changeover rates Keep to the formula WNR = W (0) exp(-alphap), wherever p is the amount of phonons matching the Electricity gap. The nonradiative transition premiums of Er3+ show temperature dependence in step with the multiphonon peace theory. In Tm3+ the temperature dependence of nonradiative rest premiums is https://andersoncedaw.develop-blog.com/40187620/not-known-factual-statements-about-er-yb-yab-crystal
