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 costs of Er3+ show temperature dependence in line with the multiphonon rest principle. In Tm3+ the temperature dependence of nonradiative peace prices is https://trentonkljgc.acidblog.net/64391286/details-fiction-and-er-yb-yab-crystal
