The spectroscopic properties in VUV-vis range for phosphors calcium and gadolinium double borate Ca{sub 3}Gd{sub 2}(BO{sub 3}){sub 4} doped with rare-earth ions Ce{sup 3+}, Sm{sup 3+}, Eu{sup 3+} and Tb{sup 3+} were investigated. The host-related absorption, the f-d transitions of Ce{sup 3+} and Tb{sup 3+}, as well as the charge transfer transitions of Sm{sup 3+} and Eu{sup 3+} in the host lattice are assigned and discussed. The CIE chromaticity coordinates for Eu{sup 3+}- and Tb{sup 3+}-activated phosphors are calculated.
