Translucent Cerium Fluoride Ceramics Fabricated By Hot- Pressing For Scintillation Application

In this study, translucent CeF3 ceramics was firstly fabricated by hot-pressing, aiming to develop an economical, radiation hard scintillation material. After sintering at 950 degrees C and pressure exertion of 300MPa for 2h, a transmittance of 10-25% was achieved in the visible region, through a thickness of 0.75mm. Microstructure investigations indicated the average grain size was around 42.7m, 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.
