Abstract

The luminescent properties of Ce^3+^ ions in Ca~2~B~5~O~9~Cl have been studied upon excitation in the 3.5–25 eV region. The energies of all 5d crystal field levels of Ce^3+^ ions in double doped Ca~2~B~5~O~9~Cl:Ce^3+^, Na^+^ have been determined. In addition to the 4f → 5d excitation bands, the excitation spectrum of the Ce^3+^ emission shows a band with a maximum at 7.7 eV, which is attributed to the absorption of the borate groups. The influence of the structural features of Ca~2~B~5~O~9~Cl on the luminescent behavior of Ce^3+^ is discussed. (© 2006 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
