| abstract |
The invention relates to a ceramic material (14) for generating light when irradiated with radiation. Therein, the ceramic material comprises a stack (15, 16) of layers with different compositions and/or different dopants. The ceramic material can be used in a spectral computed tomography (CT) detector to detect X-rays in the spectrum, or the ceramic material can be used as a ceramic gain medium for a laser, making it possible to reduce the Temperature gradient and corresponding thermomechanical stress. |
