Designing an aromatic moiety-free neutral luminescent manganese(ii) halide scintillator for efficient X-ray imaging

Abstract

An aromatic moiety-free strategy is proposed for the effective excited state manipulation of the neutral luminescent manganese(II) halide. Interestingly, compared to the traditional monodentate ligand-based manganese(II) complexes, a dramatic enhancement of photoluminescent quantum yield of 0.413 is achieved by incorporating tri(pyrrolidin-1-yl)phosphine oxide (TPPO) as a new ligand without any aromatic moiety into the manganese(II) complex. The designed aromatic moiety-free neutral luminescent manganese(II) bromide (TPPOMnBr2) featuring an intense green emission (512 nm) and a short emission lifetime (0.564 ms) is employed to realize efficient X-ray imaging with a high spatial resolution value of 11.3 lp mm−1 and a low detection limit of 34.95 nGy s−1, making it a promising candidate for high-performance X-ray detection in the future.
