  • Scintillator and radiation detector, and radiation inspecting device
    Patent number: 7498579
    Abstract: A scintillator, characterized in that it comprises crystals of Pr1-xCexF3 [wherein 0<x<0.5]. It emits a light in ultraviolet and visible regions when it is irradiated with a light or a radiation. The scintillator uses a material which exhibits improved performance with respect to the strength in light emission and to the speed in attenuation, and further is relatively easy in the growth of its crystal.
    Type: Grant
    Filed: August 25, 2004
    Date of Patent: March 3, 2009
    Assignee: Stella Chemifa Corporation
    Inventors: Tsuguo Fukuda, Hirohisa Kikuyama, Tomohiko Satonaga, Hikaru Koike
