Abstract

Photostimulated luminescence (PSL) measurements on Ce-doped BaCl 2 single crystals show a resolved (349, 373) nm doublet after X-irradiation that can be attributed to Ce3+. A similar doublet is observed in the ultraviolet-excited photoluminescence (PL) and the X-ray excited luminescence (XL). The PSL stimulation arises from F-centre absorption. PL, XL, and PSL are also observed in an annealed Ce-doped fluorochlorozirconate glass-ceramic that contains BaCl2 crystallites. However, the spectral features are different from those found in our Ce-doped BaCl2 single crystals. We conclude that most of the Ce remains in the glass matrix.
