The use of such a structure simplifies the manufacturing of a scintillator. The radiation detector reduces the number of reflecting plate lattices that are stacked when manufacturing the scintillator, enabling the scintillator to be manufactured easily. Moreover, the number of reflecting plate lattices to be manufactured is reduced, reducing commensurately the number of components required for manufacturing the scintillator. The scintillator may be manufactured more easily and an inexpensive radiation detector may be obtained.

  • Publication number: 20100230615
    Abstract: A security device for authenticating bank notes, documents and other items, comprises a luminescent material for producing luminescent radiation of first and second wavelengths. The security device includes an optically variable structure for controlling emission of luminescent radiation of at least one of the first and second wavelengths from the security device, the security device being arranged to permit, from an area of the optically variable structure, emission of luminescence of the first and second wavelengths from the security device. The optically variable structure causes the relative emissivity of the security device for luminescent radiation of the first and second wavelengths to change with a change in emission angle, so that the security device produces an angle-dependent colour shift in the emitted luminescent radiation.

  • Patent number: 7795600
    Abstract: A wavelength conversion chip is formed by depositing a wavelength conversion material on a substrate to form a layer, removing the resulting wavelength conversion layer from the substrate and then segmenting the wavelength conversion layer into a plurality of wavelength conversion chips. The wavelength conversion material can be annealed by thermal annealing or radiation annealing to increase the wavelength conversion efficiency of the chips or to sinter the wavelength conversion material to form a ceramic material. Optical coatings, vias, light extraction elements, electrical connections or electrical bond pads can be fabricated on the wavelength conversion chips.

  • Publication number: 20100213391
    Abstract: High-power excimer lasers are assembled with individually replaceable optical module subsystems containing consumable optical components. Windows formed in the enclosures of the optical modules incorporate a fluorescent material for converting ultraviolet light scattered from the components of the optical module into visible light emanating from the windows. Changes in the amount or location of the visible light emanating from the windows are interpreted as indications of the degradation in the performance of the optical modules.

  • Publication number: 20100072398
    Abstract: A method of forming a scintillator device includes inserting a window into a lumen of a window support ring. The window support ring has an annular structure defining the lumen. The lumen extends between first and second ends of the window support ring. The method also includes inserting a scintillator material into a cavity of a housing defined by an annular sidewall of the housing. The housing has an anterior end and a posterior end. The sidewall defines an opening at the anterior end of the housing. The scintillator material is inserted into the cavity via the opening. The method further includes adhering the window to a front face of the scintillator material and coupling the first end of the window support ring to the annular sidewall of the housing at the anterior end to close the opening.
