The present invention provides a scintillator panel which is capable of utilizing light emitted by a phosphor at a high efficiency due to particles having a high refractive index being dispersed within a scintillator layer in a favorable state, which thus allows for a marked reduction in the amount of radiation exposure to a subject or the like, and which has a high luminance. The present invention also provides a scintillator panel including a substrate, and a scintillator layer containing metal compound particles and a phosphor, wherein the phosphor is covered by the metal compound at a coverage ratio of 5% or more.

Scintillator panel, radiation detector, and manufacturing method therefor

Disclosed are: a paste for an electron emission source, which enables omission of an activation process and is capable of emitting electrons at a low voltage, while exhibiting excellent adhesion to a cathode substrate; and an electron emission source which uses the paste for an electron emission source. Specifically disclosed is an electron emission source which is produced by subjecting a paste for an electron emission source containing the components (A)-(C) described below to a heat treatment. The electron emission source has cracks and carbon nanotubes project from the surfaces of the cracks. (A) carbon nanotubes (B) glass powder (C) at least one substance selected from the group consisting of metal salts, metal hydroxides, organic metal compounds, metal complexes, silane coupling agents and titanium coupling agents.

Paste for electron emission source, and electron emission source

The present invention provides a producing method of powder particles having an average particle diameter on the order of submicrons. Specifically, the producing method is a producing method of powder particles obtained by grinding a product to be ground by using plural grinding media, wherein the grinding media including at least one kind (grinding medium A) having an average particle diameter of 0.01 to 5 times and at least one kind (grinding medium B) having an average particle diameter of 10 to 450 times, with respect to the average particle diameter of the product to be ground before being ground, are used.

Producing method of powder particles by using grinding medium

An object of the present invention is to provide a paste for an electron emission source, which can retain good electric contact between CNT and a cathode electrode, by containing an electrically conductive particle having a particle diameter within the optimal range. A paste for an electron emission source containing a carbon nanotube having a diameter of 1 nm or more and less than 10 nm, and an electrically conductive part having an average particle diameter of 0.1 to 1 &#x3bc;m.
