X-RAY SCINTILLATOR CONTAINING A MULTI-LAYERED COATING

摘要

There is provided an x-ray scintillator (10) including a pore matrix having a plurality of pores formed in a substrate (1). Each of the pores is at least partially covered with a multi-layered coating including at least a reflective layer (2) and a protective layer (3). The at least partially coated pores are filled with scintillating material (4) for absorbing x-ray photons to produce secondary photons, preferably with a wavelength in the visible range. The reflective layer (2) of the multi-layered coating is arranged between the scintillating material (4) and the substrate (1) for reflecting the secondary photons, and the protective layer (3) of the multi-layered coating is arranged between the reflective layer (2) and the scintillating material (4) for protecting the reflective layer while allowing reflection of the secondary photons by the reflective layer.
