The nonradiative changeover fees follow the formula WNR = W (0) exp(-alphap), the place p is the amount of phonons matching the energy hole. The nonradiative changeover rates of Er3+ exhibit temperature dependence in keeping with the multiphonon relaxation concept. In Tm3+ the temperature dependence of nonradiative leisure costs is https://erybyabcrystal31976.blogacep.com/38409953/details-fiction-and-er-yb-yab-crystal
