Paper Abstract

New aspects of RCOB structure were obtained from Eu3+ absorption/emission spectra in GdCOB and EuCOB host lattices. The spectra of Eu3+ in powders and single crystals are comparatively analyzed. The Eu3+ spectra show at least three non-equivalent centers whose static spectral characteristics were used to assign structural modes. An explanation of the difference between GdCOB: Eu3+ and EuCOB spectra in terms of a disordered occupancy of rare earth and calcium sites is given.
