The nonradiative changeover rates Keep to the formula WNR = W (0) exp(-alphap), where by p is the amount of phonons matching the Electricity gap. The nonradiative transition premiums of Er3+ show temperature dependence in line with the multiphonon rest principle. In Tm3+ the temperature dependence of nonradiative peace prices https://er-yb-yab-crystal41628.topbloghub.com/39496260/considerations-to-know-about-er-yb-yab-crystal
