X-ray scintillator containing a multi-layered coating

An x-ray scintillator comprising a pore matrix having a plurality of pores formed in a substrate, wherein each of said pores is at least partially covered with a multi-layered coating comprising at least a reflective layer and a protective layer,

• wherein said at least partially coated pores are filled with scintillating material for absorbing x-ray photons to produce secondary photons, said at least partially coated pores are filled with scintillating material through a melting process such that the filled pores include solidified, melted scintillating material,
• wherein said reflective layer of said multi-layered coating is arranged between the scintillating material and the substrate for reflecting the secondary photons, and
• wherein said protective layer of said multi-layered coating is arranged between the reflective layer and the scintillating material for protecting the reflective layer while allowing reflection of the secondary photons by the reflective layer,
• wherein the protective layer is substantially optically inactive with respect to the secondary photons so that the protective layer does not have any significant optical effect on the secondary photons, and
• the multi-layered coating is constructed such that the multi-layered coating withstands, without degradation, the melting process used to fill the pores with scintillating material.
