Abstract: Fluoride phosphate glass has the ability to detect ionizing radiation, and thus can be utilized in various forms for the purposes of dosimetry. To further understand the potential of this material, the luminescence properties have been studied using techniques such as thermoluminescence (TL)and optically stimulated luminescence (OSL). Short luminescent lifetimes and shallow electron trap depths were measured. At the main TL peak at 60 ºC, the activation energy was calculated to be 0.5 eV with a frequency factor of 1.9x106 s-1 and lifetime of 2.1x102 s at 293 K. Fast timing results yield an OSL rise-time of 12.2 μs. Results indicate the material studied is well suited for monitoring applications where the time between radiation exposure and OSL read-out is in the order of several minutes.
