Abstract: Optically stimulated luminescence has been demonstrated within a fluoride phosphate glass optical fibre. These fibres have been used as the basis of a novel dosimeter architecture whereby the optical fibre acts as both the sensing and light guiding component. Fibres were fabricated from a commercially acquired glass and irradiated using a 90Sr/90Y source. Following optical stimulation with a 532 nm laser, optically stimulated luminescence of 483 ± 18 cnts/g/μJ was detected. In addition to OSL, scintillation of 6155 ± 78 cnts/s was also measured. A linear response between 0.16 - 2 Gy of irradiation was measured, after which the intensity was observed to plateau. These results indicate the potential suitability of fluoride phosphate optical fibres for radiation sensing applications.
