Study on the emission property of YBO3 with co-doping of Ce and Gd ions

Abstract

We investigated the co-doping effect of Ce3+ and Gd3+ ions on the visible emission in vaterite-type orthoborate YBO3. By using photoluminescence and photoluminescence excitation spectroscopy, we found that the co-doping of the Gd3+ ions increased the violet-blue emission of the Ce ions significantly. In basis of the optical spectroscopic data, we discussed our results in terms of the energy transfer between Ce3+ and Gd3+ ions.
