The absolute intensities of transitions occurring in the optical spectra of single crystals of Y2O3 doped with small amounts of Pr, Nd, Eu, Er, and Tm; single crystals of LaF3 doped with small amounts of Pr and Nd; and single crystals of Er2O3, Tm2O3, and Yb2O3 have been measured at room temperature. All observed transitions occur within the ground configurations of the trivalent rare-earth ions, and their intensities are accounted ...
