Abstract
The interpretation of complex Yb3+ optical spectra in non-linear gadolinium calcium oxoborate GdCa4O(BO3)3-GdCOB crystals is still contradictory. The electronic structure of two Yb3+ centers in GdCOB is analyzed, including a crystal field parametric calculation for the main center. The possible models for vibronics intensities are discussed. The presence of a minor center whose relative intensity is of ~10%, indepenent on Yb3+ content, and Gaussian line-shapes are connected to the RCOB crystal disordered structure proposed recently from X-ray data.
