(JP6092732) PROBLEM TO BE SOLVED: To provide a dense high-speed scintillator material of low afterglow.SOLUTION: An inorganic scintillator material is represented by formula Lu)YCeMSiM'O, (wherein M represents a divalent alkaline earth metal and M' represents a trivalent metal, (z+v) being 0.0001-0.2; z being 0-0.2; v being 0-0.2; x-0.0001-0.1; and y ranging from (x+z) to 1). In particular, this material may equip scintillation detectors for applications in industry, for the medical field (scanners) and/or for detection in oil drilling. The presence of Ca in the crystal reduces the afterglow, while stopping power for high-energy radiation remains high.
