The nonradiative changeover costs follow the system WNR = W (0) exp(-alphap), exactly where p is the quantity of phonons matching the energy gap. The nonradiative changeover rates of Er3+ exhibit temperature dependence per the multiphonon rest principle. In Tm3+ the temperature dependence of nonradiative peace rates is intricate by https://hubbardl148yqk9.tokka-blog.com/profile
