Problems solved by technology

However, when the width of the partition wall is widened, the space between the partition walls is relatively narrowed, the volume that can be filled with the X-ray phosphor becomes smaller, and the filling amount is not uniform.
Therefore, the amount of X-ray phosphors in the scintillator panel obtained by this method is small, so there are disadvantages such as weak light emission and uneven light emission.
These factors can affect clear shots in low-dose photography

Embodiment 1)

[0140] On a glass substrate (AGC Asahi Glass Co., Ltd.; AN-100) of 500mm×500mm×thickness 0.5mm, the above-mentioned base paste was coated with a 15μm bar coater, dried at 150°C for 30 minutes, and heat-cured. A base paste film with a thickness of 12 μm was formed. Next, the photosensitive paste for partition walls was coated with a die coater so as to have a dried thickness of 500 μm, and dried at 120° C. for 30 minutes to form a photosensitive paste coating film for partition walls.

[0141] Next, through a photomask (a chrome mask having grid-like openings with a line width of 10 μm and a vertical and horizontal pitch of 125 μm) formed with openings corresponding to the desired partition rib pattern, the photomask was heated at 700 mJ / cm using an ultra-high pressure mercury lamp. 2 The exposure amount of the photosensitive paste coating film for partition walls was exposed. The exposed photosensitive paste coating film for barrier ribs was developed in 0.5% aqueous ethanola...

Embodiment 2)

[0150] A substrate on which lattice-shaped partition walls were formed was produced by the same method as in Example 1. After apply|coating the said paste 2 for photosensitive reflection layers to the whole surface of a partition by the screen printing method, it dried at 120 degreeC for 30 minutes. Next, a mask having openings corresponding to the desired reflective layer formation pattern (both vertical and horizontal pitches are 125 μm; 125 μm square openings and light-shielding sections are alternately arranged) is arranged so that the openings coincide with the cells, Use an ultra-high pressure mercury lamp at 500mJ / cm 2 Exposure at the exposure level. The exposed photosensitive reflective layer paste coating film was developed in a 0.5% ethanolamine aqueous solution to remove unexposed portions to form a grid-like photosensitive reflective layer paste coating film pattern. Furthermore, it baked in air at 500 degreeC for 15 minutes. The result is as figure 2 As shown...

Embodiment 3)

[0153] By the same method as in Example 1, the base paste film and the photosensitive paste coating film for partition walls were formed on the glass substrate.

[0154] Next, exposure and exposure were performed under the same conditions as in Example 1 through a photomask (a photomask having stripe-shaped openings with a pitch of 125 μm and a line width of 10 μm) in which openings corresponding to the desired partition rib pattern were formed. Developed to form a striped photosensitive paste coating film pattern. Furthermore, the photosensitive paste coating film pattern was calcined in air at 595° C. for 15 minutes to produce a film having a partition wall spacing L2 of 125 μm, a top width L4 of 15 μm, a bottom width L3 of 30 μm, and a partition wall height L1 formed on the surface. A substrate with stripe-shaped partition walls of 330 μm and a size of 480 mm×480 mm. The transmittance of light having a wavelength of 550 nm at a thickness of 30 μm of the partition wall was ...

Abstract

The present invention provides a scintillator panel that achieves clear image quality, has high light emitting efficiency, and at which a narrow partition wall is formed at a high precision on a large area. The present invention provides a scintillator panel having a flat plate-shaped substrate, a partition wall provided on the substrate, and a scintillator layer comprising a fluorescent body filling the inside of cells partitioned by the partition wall, wherein a reflecting layer is formed only at one lateral side of the partition wall.

Description

technical field [0001] The present invention relates to a scintillator panel used for a radiation detection device used in a medical diagnostic device, a non-destructive inspection instrument, and the like. Background technique [0002] Conventionally, X-ray images using films have been widely used in medical fields. However, since X-ray images using films are analog image information, digital radiation detection devices such as computed radiography (CR) and flat panel detectors (flat panel detector: FPD) have been developed in recent years. . [0003] A scintillator panel is used in a flat panel X-ray detection device (FPD) to convert radiation into visible light. The scintillator panel contains X-ray phosphors such as cesium iodide (CsI), and the X-ray phosphors emit visible light according to the irradiated X-rays, and the light passes through TFT (thin film transistor, thin film transistor), CCD (charge-coupled device, charge-coupled device) and converted into electri...
