The nonradiative changeover rates Keep to the system WNR = W (0) exp(-alphap), exactly where p is the quantity of phonons matching the energy hole. The nonradiative transition premiums of Er3+ show temperature dependence in line with the multiphonon rest concept. In Tm3+ the temperature dependence of nonradiative rest prices https://erybyabcrystal73962.develop-blog.com/39964846/5-simple-statements-about-er-yb-yab-crystal-explained
