Abstract
Disclosed herein is a scintillator comprising a plurality of garnet compositions in a single block having the structural formula (1): M1aM2bM3cM4dO12 (1) where O represents oxygen, M1, M2, M3, and M4 represents a first, second, third and fourth metal that are different from each other, where the sum of a+b+c+d is about 8, where “a” has a value of 2 to 3.5, “b” has a value of 0 to 5, “c” has a value of 0 to 5 “d” has a value of 0 to 1, where “b” and “c”, “b” and “d” or “c” and “d” cannot both be equal to zero simultaneously, where M1 is rare earth element including gadolinium, yttrium, lutetium, or a combination thereof, M2 is aluminum or boron, M3 is gallium and M4 is a codopant; wherein two compositions having identical structural formulas are not adjacent to each other and wherein the single block is devoid of optical interfaces between different compositions.
