<P>PROBLEM TO BE SOLVED: To increase the amount of light received by a photoelectric conversion layer. <P>SOLUTION: The radiation detector includes: a scintillator layer 24 formed into a single layer by mixing a first fluorescent material 26 for converting radiation X into light 26A of a first wavelength mainly in response to the radiation X of first energy, and a second fluorescent material 28 for converting radiation X into light 28A of a second wavelength mainly in response to radiation X2 of second energy; a first photoelectric conversion layer 30 which is arranged in a side closer to an irradiation surface 300 of the radiation X than the scintillator layer 24, is constituted by a first organic material, absorbs more the light 26A of the first wavelength than the light 28A of the second wavelength, and converts the light into a charge Q1; and a second photoelectric conversion layer 34 which is constituted by a second organic material different from the first organic material, absorbs more the light 28A of the second wavelength than the light 26A of the first wavelength, and converts the light into a charge Q2. <P>COPYRIGHT: (C)2012,JPO&INPIT |
