Title:
RADIATION DETECTOR AND MANUFACTURING METHOD FOR SAME
Document Type and Number:
WIPO Patent Application WO/2012/014706
Kind Code:
A1
Abstract:
The disclosed detector is thin and can obtain two radiation images by means of a signal irradiation of radiation. The disclosed detector is configured of: a scintillator layer wherein a first fluorescent material which is mainly sensitive to low energy radiation and which converts the radiation into light of a first wavelength, and a second fluorescent material which is mainly sensitive to high energy radiation and which converts the radiation into light of a second wavelength having a different peak to the first wavelength are mixed or are separately present; and an organic photoelectric conversion layer wherein a plurality of first light detection sensors, which are formed from an organic material and which absorb more of the light of the first wavelength than light of the second wavelength and convert said light into electrical charge, and second light detection sensors, which are formed from an organic material which is different from the abovementioned organic material, and which absorb more of the light of the second wavelength than light of the first wavelength and convert said light into electrical charge, are arranged in the same plane. In the detector the scintillator layer and the organic photoelectric conversion layer are laminated in the radiation (X) incidence direction.
