Abstract: Fluoride phosphate (FP) glass fibres have been developed for radiation dosimetry based on the mechanism of optically stimulated luminescence (OSL). Doping with Tb³⁺ ions improved the materials sensitivity; for samples melted in oxidising conditions, OSL intensity was increased from 8.8 × 10⁵ cnts/g/Gy for undoped glass to 812.3 × 10⁵ cnts/g/Gy for Tb³⁺-doped glass. The radiation sensor performance of Tb³⁺-doped glass fibres under both beta and X-ray irradiation demonstrated the capability of the fibres for radiation dosimetry applications.
