Abstract
A reflective resin sheet is bonded to one face of a supporting substrate transmitting a radiation ray and a resin sheet of the same material as that of the reflective resin sheet to the other face of the supporting substrate. A phosphor layer converting a radiation ray into visible light is formed additionally on the reflective resin sheet formed on one face of the supporting substrate. The phosphor layer is enclosed with an additional moisture-proof layer and the reflective resin sheet. It is possible to obtain a scintillator panel higher in sensitivity characteristics, stabilized in quality and more cost-effective by placing the reflective resin sheet between the supporting substrate and the phosphor layer.
Claims4
A scintillator panel comprising:
- a supporting substrate which transmits a radiation ray;
- a reflective resin sheet formed directly on top of one face of the supporting substrate, the reflective resin sheet having a single layer made from foamed resin;
- and
- a phosphor layer which is formed directly on top of the reflective resin sheet disposed on the one face of the supporting substrate and converts the radiation ray into visible light.
A scintillator panel comprising:
- a supporting substrate which transmits a radiation ray;
- a reflective resin sheet formed on at least one face of the supporting substrate, the supporting substrate being made of carbon fiber-reinforced plastic (CFRP) impregnated with thermosetting resin, the reflective resin sheet having a single layer, the single layer being an expanded resin layer or dispersed with a grain of heterogeneous substance different from the resin in the resin sheet;
- and
- a phosphor layer which is formed on the reflective resin sheet on one face of the supporting substrate and converts the radiation ray into visible light,
- wherein the reflective resin sheet is bonded by resin, which is originally impregnated in a base material of CFRP before heat curing, to the CFRP supporting substrate.
