In this study, translucent CeF 3 ceramics was firstly fabricated by hot‐pressing, aiming to develop an economical, radiation hard scintillation material. After sintering at 950°C and pressure exertion of 300 MP a for 2 h, a transmittance of 10–25% was achieved in the visible region, through a thickness of 0.75 mm. Microstructure investigations indicated the average grain size was around 42.7 μm, with no obvious pores observed on the fracture surface. The X‐ray luminescence spectra, decay time, and thermoluminescence spectra were measured, and the results of the ceramics were similar to its corresponding single crystals, which proved it to be a promising scintillation material.
