The nonradiative changeover rates Keep to the formulation WNR = W (0) exp(-alphap), in which p is the volume of phonons matching the Vitality hole. The nonradiative changeover prices of Er3+ exhibit temperature dependence according to the multiphonon relaxation concept. In Tm3+ the temperature dependence of nonradiative leisure rates is https://er-yb-yab-crystal16049.blogocial.com/not-known-details-about-er-yb-yab-crystal-68963735
