Patent number: 7705315Abstract: An Ag film as a light-reflecting film is formed on one surface of an a-C substrate of a scintillator panel. The entire surface of the Ag film is covered with an SiN film for protecting the Ag film. A scintillator having a columnar structure, which converts an incident radiation into visible light, is formed on the surface of the SiN film. The scintillator is covered with a polyparaxylylene film together with the substrate.Type: GrantFiled: June 16, 2008Date of Patent: April 27, 2010Assignee: Hamamatsu Photonics K.K.Inventors: Takuya Homme, Toshio Takabayashi, Hiroto Sato, Takaharu Suzuki, Yoshio Natsume
