S&M4325 Research paper https://doi.org/10.18494/SAM6031 Published: February 6, 2026 Scintillation Properties of Eu:CaS Transparent Ceramicsfor Radiation Imaging Applications [PDF] Hiromi Kimura, Takeshi Fujiwara, Hidetoshi Kato, Takumi Kato, Toshiaki Kunikata, Noriaki Kawaguchi, and Takayuki Yanagida (Received October 31, 2025; Accepted December 12, 2025) Keywords: radiation-induced luminescence, scintillators, X-ray imaging detectors
CaS transparent ceramics doped with various concentrations of Eu (0.01, 0.05, 0.1, and 0.5%) were synthesized by the spark plasma sintering method, and their structural, optical, and X-ray-induced scintillation properties were evaluated. The ceramics exhibited high transmittance (~80%) with absorption bands corresponding to the 4f–5d transitions of Eu2+ ions at 300–350 nm and 400–600 nm. Under UV and X-ray excitation, a broad emission peak at around 650 nm was observed, which would be due to the 5d–4f transitions of Eu2+ ions. The practical applicability of the 0.05% Eu-doped CaS transparent ceramic was demonstrated through X-ray imaging of electronic components. The X-ray imaging system achieved a spatial resolution of at least 0.15 mm.
