Abstract
A luminescent body is for an X-ray detector, in particular for an X-ray computer tomograph. It contains a ceramic of the general composition (M1-xLnx)2O2S, M being at least one element selected from the group: Y, La, Sc, Lu and/or Gd, and Ln being at least one element selected from the group: Eu, Ce, Pr, Tb, Yb, Dy, Sm and/or Ho. In order to improve the spatial resolution of the luminescent body, the ceramic is used in the form of fibers, which are connected in a parallel alignment to constitute a fiber plate.
