The nonradiative changeover rates Keep to the components WNR = W (0) exp(-alphap), where by p is the amount of phonons matching the energy hole. The nonradiative changeover rates of Er3+ show temperature dependence in keeping with the multiphonon rest concept. In Tm3+ the temperature dependence of nonradiative peace rates https://er-yb-yab-crystal52962.blog-eye.com/34951184/what-does-er-yb-yab-crystal-mean
