摘要
V centers (hole centers) and hole-photostimulated luminescence of BaFCl crystal are reported for the first time. The absorption bands of V1, V2 and V3 centers are peaking at 205, 238 and 355 nm respectively. V2 center creation by X-irradiation and decay during photostimulated luminescence process are synchronousl with that of F center. This indicates that V centers play the same roles as F centers in X-ray storage and photostimulated luminescence processes.
