چکیده انگلیسی
In this paper, we report basic optical properties and scintillation and storage luminescence properties of MgF2:Ce transparent ceramics with different doping concentrations of Ce (0.01, 0.1 and 1%) synthesized by spark plasma sintering (SPS). In scintillation, thermally-stimulated luminescence (TSL) and optically-stimulated luminescence (OSL), the dominant emissions were due to the 5d-4f transitions of Ce3+ which appeared in the near-UV region peaking around 320 and 360Â nm. The scintillation was evaluated by X-ray irradiation while OSL was observed under 540Â nm stimulation. In particular, the TSL sensitivity was high and showed a good linearity from 0.1Â mGy to 1000Â mGy.
