The development of composite scintillating materials is necessary for the optimization of advanced pixelated X-ray imaging technology. Polycrystalline BaFCl:Eu²⁺ was synthesized via a flux growth technique and its emission properties were characterized through photo-luminescence (PL) spectroscopy and time-correlated single photon counting (TCSPC). PL emission wavelengths were observed at 365 nm, 383 nm, and 430 nm under UV excitation. Composite pastes, consisting of BaFCl:Eu²⁺ powder and NOA1665 UV-curable resin, were fabricated and subsequently analyzed through absorption and radio-luminescence (RL) spectroscopy. An interchange of transmissivity and light production, resulting from differences in the amount of solvent and resin in the composite, was observed in fabricated composites.
