The nonradiative changeover rates Keep to the formula WNR = W (0) exp(-alphap), wherever p is the number of phonons matching the Electricity hole. The nonradiative transition premiums of Er3+ show temperature dependence in line with the multiphonon leisure principle. In Tm3+ the temperature dependence of nonradiative rest premiums is https://emilianodgklj.blogvivi.com/33885689/a-review-of-er-yb-yab-crystal
