1. An inorganic LYSO-type scintillator material comprising Lu, Y, Si, O, Ce, M, and optionally M′ wherein:
the relative amounts of Lu, Y, Si, O, Ce, M, and M′ satisfy formula (1):
Lu(2-y)Y(y-z-x)CexMzSi(1-v)M′vO5  (1);
M represents a divalent alkaline earth metal and M′ represents a trivalent metal;
(z+v) is greater than or equal to 0.0001 and less than or equal to 0.2;
z is greater than 0 and less than or equal to 0.2;
v is greater than or equal to 0 and less than or equal to 0.2;
x is greater than or equal to 0.0001 and less than 0.1; and
y is from (x+z) to 1.
