Abstract
Organic manganese halides encompass the excellent attributes of low cost, environmental friendliness, and high quantum efficiency, making them highly regarded as a novel scintillating material with tremendous potential in the field of X-ray detection. Nevertheless, the issue of poor stability has impeded their practical application. This article introduces a novel scintillator based on [(CH3)4N]2MnBr4 nanocrystal films. Here, we employed the evaporation crystallization method to synthesize a [(CH3)4N]2MnBr4 sample, with the emission peak located at 527 nm. To enhance their stability, we optimized by doping various concentrations of Zn2+ and achieved the most stable sample, [(CH3)4N]2Mn0.6Zn0.4Br4, with an impressive 84.1% high photoluminescence quantum efficiency. Furthermore, we used the sandwich method to create [(CH3)4N]2Mn0.6Zn0.4Br4@PET films, effectively improving stability. The X-ray imaging performance of [(CH3)4N]2Mn0.6Zn0.4Br4@PET films was evaluated, and it is worth noting that the films exhibited a notably high radioluminescence intensity, achieving a spatial resolution of 9.8 lp mm–1. This indicates that PET films prepared from [(CH3)4N]2MnBr4 powder can serve as a candidate material for high-resolution scintillators, providing an excellent visualization tool for X-ray imaging.
