Abstract

A scintillator panel including a substrate and a scintillator layer provided on the substrate, the layer including a plurality of columnar structures, wherein the plurality of columnar structures are independent of each other via a gap, and the columnar structures are irradiation products.

First claim

What is claimed is:

1 . A scintillator panel comprising:
a substrate; and a scintillator layer provided on the substrate, the layer comprising a plurality of columnar structures, wherein the plurality of columnar structures are independent of each other via a gap,
and the columnar structures are irradiation products.

2 . The scintillator panel according to claim 1 , wherein the columnar structures are each a laminate of a plurality of resin layers each comprising scintillator particles and a resin.

3 . The scintillator panel according to claim 2 , wherein the scintillator layer satisfies the relationships 0.1≦B/A≦20.0 and 2.0≦C/A, wherein A is an interval (μm) between the adjacent columnar structures; B is a length (μm) of one of the resin layers constituting a columnar structure in the direction in which the substrate and the resin layers are laminated; and C is a diameter (μm) of the inscribed circle of a columnar structure viewed from above the substrate.

4 . The scintillator panel according to claim 2 , wherein B, the length of one of the resin layers constituting each columnar structure in the direction in which the substrate and the resin layers are laminated, is in the range of 10 to 200 μm.

5 . A radiation detector comprising:
a sensor substrate (I) having a plurality of light-receptive pixels; and the scintillator panel according to claim 1 , the sensor substrate (I) and the scintillator layer facing each other.

6 . A radiation detector comprising:
the scintillator panel according to claim 1 , wherein the substrate is a sensor substrate (I) having a plurality of light-receptive pixels; and a substrate (II) on which a plurality of light-receptive pixels are not formed.

7 . A method for manufacturing a scintillator panel, comprising:
Step I: forming a photosensitive paste layer from a photosensitive paste comprising at least scintillator particles and a photosensitive component, and exposing the photosensitive paste layer using a photomask to form a given pattern; and Step II: removing developer-soluble portions of the exposed photosensitive paste layer.

8 . The manufacturing method according to claim 7 , wherein the Step I is repeated twice or more before the Step II.
