A monocrystalline scintillator comprises a monocrystal and an optical plate wherein a first side of the monocrystal is adhered to the optical plate. The monocrystal comprises at least one of a rare earth garnet, a perovskite crystal, a rare-earth silicate, and a monocrystal oxysulphide. The scintillator assembly includes an adhesive adhering the optical plate to the first side of the monocrystal. The adhesive can comprise an ultra-high vacuum compatible adhesive. The adhesive is substantially transparent and has a refractive index matching the optical plate. The scintillator assembly can also include a reflective coating on the second side of the monocrystal. The monocrystalline scintillator assembly can be incorporated in a microchannel plate image intensifier tube to provide improved spatial resolution and temporal response.

The present invention is in the field of an improved scintillator for X-rays, use of the inventive scintillator, an X-ray detector comprising the present scintillator, and a method of producing an improved scintillator. A scintillator converts X-rays into visible light; high performance scintillators are typically made of a crystalline material.

An object of the present invention is to provide a radiological image conversion screen where the flexibility and the storage stability of the radiological image conversion screen are sufficiently kept without phthalic acid ester while conventional sensitivity and sharpness being maintained, and another object thereof is to provide a radiological image conversion screen where a plasticizer in a phosphor layer is suppressed from volatilization and from transfer to other layers and/or films. The objects are solved by a radiological image conversion screen comprising a support substrate and a phosphor layer stacked on the support substrate, wherein the phosphor layer comprises phosphor particles, a polyvinyl acetal resin, and a carboxylic acid ester having an ether group.

A radiation detector includes: a scintillator panel having a scintillator layer; and a photoelectric conversion panel having a support substrate, a light receiving element, and a switching element, wherein the light receiving element faces the scintillator layer, the photoelectric conversion panel has flexibility, and the scintillator layer is formed by being sealed with a moisture-proof material.

A neutron conversion foil for being used in a neutron detector includes a substrate having a first and second side. The substrate is covered at least on one of the first and second sides with a neutron conversion layer made of a neutron reactive material and being capable of capturing neutrons to thereafter emit light and/or charged particles. The neutron conversion foil is transparent to light such that light originating from the conversion of neutrons can pass through one or several of the neutron conversion foils and thereafter be collected and detected by a light sensing device.

A radiation image conversion panel includes: a substrate; a metal oxide layer formed on the substrate, including conductivity, and including a rough surface; a first organic resin layer formed on the surface of the metal oxide layer; and a fluorescent layer formed on the first organic resin layer, including a plurality of columnar crystals, and configured to emit light in accordance with incident radiation.
