Abstract: The invention relates to an inorganic scintillator material of formula Lu(2?y)Y(y?z?x)CexMzSi(1?v)M?vO5, in which: M represents a divalent alkaline earth metal and M? represents a trivalent metal, (z+v) being greater than or equal to 0.0001 and less than or equal to 0.2, z being greater than or equal to 0 and less than or equal to 0.2; v being greater than or equal to 0 and less than or equal to 0.2, x being greater than or equal to 0.0001 and less than 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.
