Abstract
A scintillator material for an ionizing radiation detector comprising a halide perovskite, said perovskite having one of the following formulations: (A′)2(A)n-1[MnX3n+1] with n a positive integer between 1 and 100, inclusive, or (A′)(A)p-1[MpX3p+1] with p a positive integer between 1 and 100, inclusive, or (A′)2(A)m[MmX3m+2], with m a positive integer between 1 and 100, inclusive, or (A′)2(A)q-1[MqX3q+3], with q a positive integer between 1 and 100, inclusive; where A and A′ are organic cations, M is a metal chosen from Pb, Bi, Ge or Sn, X is a halogen or a mixture of halogens chosen from Cl, Br, and I, and wherein said perovskite further comprises at least one scintillation activating element N.
