A dicationic ionic liquid strategy to enhance the thermal stability of manganese bromide scintillators.

ABSTRACT: Conventional organic-inorganic hybrid manganese halides (Mn-OIMHs) as scintillators face challenges in thermal stability. This work proposes a strategy of introducing dicationic ionic liquids (DILs) to construct dicationic Mn-OIMHs with improved thermal stability. Comparative studies for the structures and X-ray scintillation properties are done for a series of Mn-OIMHs, that is, dicationic AMnBr₄ (A = PP214²⁺ (1,4-bis(N-methylpiperidinyl)-butane) for 1, P214²⁺ (1,4-bis(N-methylpyrrolidinium)-butane) for 3, and PP215²⁺ (1,5-bis(N-methylpiperidinyl)-pentane) for 5) and monocationic A₂MnBr₄ (A = PP14⁺ (N-methyl-N-butylpiperidinium) for 2, P14⁺ (N-methyl-N-b
