Abstract
The invention relates to a ceramic material () for generating light when irradiated with radiation, wherein the ceramic material comprises a stack of layers () having different compositions and/or different dopings. The ceramic material may be used in a spectral computed tomography (CT) detector, in order to spectrally detect x-rays, or it may be used as a ceramic gain medium of a laser such that temperature gradients and corresponding thermo-mechanical stresses within the gain medium can be reduced.
