Abstract: A luminescent composition includes a host matrix sensitized by Ce3+ and showing emission in the ultraviolet range. Typical host matrices include fluorides, sulphates, and phosphates, in particular A(Y1-x-yLuxLay)F4, A(Y1-x-yLuxLay)3F10, BaCa(Y1-x-yLuxLay)2F10, and Ba(Y1-x-yLuxLay)2F8, 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.
