  • SCINTILLATOR BASED ON LANTHANUM IODIDE AND LANTHANUM BROMIDE
    Publication number: 20100224798
    Abstract: A scintillator material has a formula La(1-x)CexBr3(1-y)I3y in which x represents a real number greater than or equal to 0.0005 and less than 1, y represents a real number greater than 0.20 and equal to or less than 0.9. This material has scintillation properties and emission properties and is useful in a scintillation-based detector for detecting radiation over a wide energy range.
