A translucent Gd 2 O 2 S:Pr ceramic scintillator with an in-line transmittance of ~31% at 512 nm was successfully fabricated by argon-controlled sintering. The starting precipitation precursor was obtained by a chemical precipitation route at 80 °C using ammonia solution as the precipitate, followed by reduction at 1000 °C under flowing hydrogen to produce a sphere-like Gd 2 O 2 S:Pr powder with an average particle size of ~95 nm. The Gd 2 O 2 S:Pr phosphor particle exhibits the characteristic green emission from 3 P 0,1 → 3 H 4 transitions of Pr 3+ at 512 nm upon UV excitation into a broad excitation band at 285-335 nm arising from 4 f  2 →4 f 5 d transition of Pr 3+ . Increasing Pr 3+ concentrations induce two redshifts for the two band centers of 4 f  2 →4 f 5 d transition and lattice absorption on photoluminescence excitation spectra. The optimum concentration of Pr 3+ is 0.5 at.%, and the luminescence quenching type is dominated by exchange interaction. The X-ray excited luminescence spectrum of the Gd 2 O 2 S:Pr ceramic is similar to the photoluminescence behavior of its particle. The phosphor powder and the ceramic scintillator have similar lifetimes of 2.93-2.99 μs, while the bulk material has rather higher external quantum efficiency (~37.8%) than the powder form (~27.2%).
