  • SCINTILLATOR STRUCTURE AND METHOD OF EVALUATING SCINTILLATOR
    Publication number: 20240069221
    Abstract: A scintillator structure includes a scintillator and a reflecting material that covers the scintillator. Here, the scintillator includes a resin and a phosphor, and a phosphor particle perimeter indicating a normalized length of an interface between the phosphor and the resin in a cross-sectional image of the scintillator is smaller than 6.25.

  • Ceramic scintillator and its production method, and scintillator array and radiation detector
    Patent number: 10207957
    Abstract: A method for producing a ceramic scintillator comprising the steps of mixing a rare earth compound with sulfuric acid and/or sulfate to cause their reaction to obtain a product; calcining the product to obtain calcined powder; reducing the calcined powder to obtain rare earth oxysulfide powder; molding the rare earth oxysulfide powder to obtain a green body; and sintering the green body; a pulverization step being conducted to adjust the particle sizes of the product and/or the calcined powder at least before the reduction step.

  • Production method of rare earth oxysulfide, ceramic scintillator and its production method, scintillator array, and radiation detector
    Patent number: 9896623
    Abstract: A production method of rare earth oxysulfide comprising a step of mixing a rare earth compound with sulfuric acid and/or sulfate in such a proportion that sulfate ions are 0.75-1.75 mol to 1 mol of a rare earth element, thereby preparing a reaction solution to obtain a product; a step of calcining the product to obtain calcined powder; and a step of reducing the calcined powder to obtain rare earth oxysulfide.
