Optically stimulated luminescence (OSL) is a well knownwell-known light emission process involving light stimulation of an insulator/semi-conductor material previously exposed to ionizing radiation. The intensity of the emitted light is proportional to the ionizing radiation dose previously absorbed by the material. Developing appropriate OSL materials for radiation detection and dosimetry is based on doping and co-doping of a host material to create defects that can act as traps and/or luminescent centers. In this context, plasmon interaction with luminescent centers from OSL materials could be a new, different, and unexplored method to achieve enhanced OSL intensity and consequently improve their sensitivity as radiation detectors. In this proposal, It Will be investigated whether it is possible to use the plasmonic properties of noble metal nanoparticles to obtain plasmon-enhanced OSL, giving rise to new and more sensitive ionizing radiation detectors and dosimeters.
