The nonradiative changeover rates follow the formula WNR = W (0) exp(-alphap), the place p is the amount of phonons matching the Vitality hole. The nonradiative transition charges of Er3+ exhibit temperature dependence in line with the multiphonon relaxation idea. In Tm3+ the temperature dependence of nonradiative leisure costs is https://janete824onm7.blogoxo.com/33283605/rumored-buzz-on-er-yb-yab-crystal
