Abstract
A luminescent composition includes a host matrix sensitized by Ceand showing emission in the ultraviolet range. Typical host matrices include fluorides, sulphates, and phosphates, in particular A(YLuLa)F, A(YLuLa)F, BaCa(YLuLa)F, and Ba(YLuLa)F, wherein A=Li, Na, K, Rb, or Cs. One or more of these luminescent compositions may be applied as a ceramic or single crystalline converter for CT, PET or SPECT scanners, or as a luminescent powder layer for x-ray intensifying screens.
