  • Radiation detector and method for producing photoconductive layer for recording thereof
    Patent number: 7488966
    Abstract: In a radiation detector, electrodes are provided on both sides of a photoconductive layer for recording. When the photoconductive layer for recording is irradiated with radiation during application of a predetermined bias voltage between the electrodes, electric charges are generated within the photoconductive layer for recording. Then, the generated electric charges are detected as an electric signal by the radiation detector. As the material for the photoconductive layer for recording, amorphous selenium having a coordination number of 1.95±0.02 is used.
    Type: Grant
    Filed: March 24, 2008
    Date of Patent: February 10, 2009
    Assignee: FUJIFILM Corporation
    Inventors: Kazuhiro Noda, Takashi Matsui, Yoshiko Hara
