摘要：
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 andM′ 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； andy 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.
