X-ray imaging capabilities play a vital role in the medical industry, thus incentivizing the need for advanced device development. BaFCl:Eu2+ is a promising material for scintillating composites applicable to pixelated X-ray imaging technology. Crystalline Eu(II)-doped BaFCl was synthesized via flux growth techniques with commercial reagents. The synthesis yield was separated into particle size subsets, and photo-luminescence (PL) spectra were obtained for each particle size range. Under UV irradiation, electronic transitions centered at 365 nm, 390 nm, and 430 nm were observed. Particle sizes <38 μm showed a significant drop in the characteristic Eu2+ ion emission and a more intense emission near 430 nm. X-ray diffraction (XRD) analysis revealed the presence of a secondary phase, Ba12F19Cl5, and demonstrated that the introduction of this phase is dependent on synthesis parameters.
