V Centers and Hole-photostimulated Luminescence of BaFBr Crystal

In Ref.[1] we reported the V centers and hole-photostimulated luminescence(HPSL) of BaFCl crystal. The result shows that the V centers play an equal role asthe F centers in the X-ray storage and photostimulated luminescence (PSL) processes.Previous research work paid much attention to the F centers but neglected the Vcenters. So the X-ray storage and PSL processes have not been revealed completelyyet. Our research work is significant as a complement to the previous documents.
