Abstract
Official abstract text for this publication.
A scintillator panel includes a substrate made of an organic material, a barrier layer formed on the substrate and including thallium iodide as a main component, and a scintillator layer formed on the barrier layer and including cesium iodide as a main component. According to this scintillator panel, moisture resistance can be improved by providing the barrier layer between the substrate and the scintillator layer.
First claim
Opening claim text (preview).
The invention claimed is: 1. A scintillator panel comprising: a substrate made of an organic material; a barrier layer formed on a main surface of the substrate and including thallium iodide as a main component; a scintillator layer formed on the barrier layer and constituted of a plurality of columnar crystals including cesium iodide with thallium added thereto as a main component; and a functional layer including a portion formed on a rear surface side of the substrate. 2. The scintillator panel according to claim 1 , wherein the functional layer is formed so as to be in contact with the rear surface of the substrate, and further comprising a protective film covering a rear surface of the functional layer. 3. The scintillator panel according to claim 1 , wherein the functional layer includes a portion formed so as to be in contact with the rear surface of the substrate and portions formed so as to be in contact with side surfaces of the substrate, and further comprising a protective film covering side surfaces of the functional layer and a rear surface of the functional layer. 4. The scintillator panel according to claim 1 , further comprising a protective film formed so as to be in contact with the rear surface of the substrate, and wherein the functional layer is formed on the protective film. 5. The scintillator panel according to claim 1 , further comprising a protective film formed so as to be in contact with the rear surface of the substrate and side surfaces of the substrate, and wherein the functional layer is formed on the protective film. 6. The scintillator panel according to claim 1 , wherein the functional layer includes an inorganic material as a main component. 7. The scintillator panel according to claim 1 , wherein the functional layer includes a metal foil. 8. A radiation detector comprising: the scintillator panel according to claim 1 ; and a sensor substrate including a photo-detection surface provided with a photoelectric conversion element receiving light generated in the scintillator panel, wherein the photo-detection surface of the sensor substrate faces the scintillator layer.
