Title:
RADIATION DETECTOR
Document Type and Number:
WIPO Patent Application WO/2012/014874
Kind Code:
A1
Abstract:
In order to increase the light receiving amount received by a photoelectric conversion layer, the disclosed detector is provided with: a scintillator layer which is constructed by mixing and forming into a single layer a first fluorescent material which is mainly sensitive to the radiation of a first energy and which converts the radiation into light of a first wavelength, and a second fluorescent material which is mainly sensitive to the radiation of a second energy and which converts the radiation into light of a second wavelength; a first photoelectric conversion layer which is arranged further to the radiation irradiation surface side than the scintillator layer, is formed from a first organic material, and which absorbs more of the light of the first wavelength than light of the second wavelength and converts said light to electrical charge; and a second photoelectric conversion layer which is formed from a second organic material which is different from the first organic material, and which absorbs more of the light of the second wavelength than light of the first wavelength and converts said light to electrical charge.
