Optically stimulated luminescence (OSL) was studied in undoped and rare-earth doped fluoride-phosphate glass. Following exposure to 90Sr/90Y beta-radiation, the samples demonstrated strong OSL in the 350-600 nm wavelength range. Here, we explore the effects of fabrication conditions and rare-earth dopants on the OSL. We found that the OSL intensity increases linearly with radiation dosage, indicating the suitability of fluoride-phosphate glass as a dosimeter material.
