  • Ceramic material for generating light
    Patent number: 10899672
    Abstract: The invention relates to a ceramic material (14) for generating light when irradiated with radiation, wherein the ceramic material comprises a stack of layers (15, 16) 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.

  • Garnet scintillator composition
    Patent number: 9777214
    Abstract: A ceramic or polycrystalline scintillator composition is represented by the formula (LuyGd3-y)(GaxAl5-x)O12:Ce; wherein y=1±0.5; wherein x=3±0.25; and wherein Ce is in the range 0.01 mol % to 0.7 mol %. The scintillator composition finds application in the sensitive detection of ionizing radiation and may for example be used in the detection of gamma photons in the field of PET imaging.

  • Scintillator material
    Patent number: 9598638
    Abstract: A gamma photon detector for detecting 511 keV PET radiation includes a scintillator host material doped with cerium. The cerium is present in a concentration of 0.1 to 1.0 mol %. Lower concentrations increase light output but also decay times which can lead to pile up issues. The higher light output enables the read out area to be decreased which reduces the pile up issues. Embodiments with a cerium concentration as low as 0.15 to 0.2 mol % and a read out area as low as 0.1 cm2 are contemplated.
