Photograph of the as grown crystal.
Absorption spectra of -doped PWO (0.1%Pr and 1%Pr) measured on 30 mm long cylinders. The inset provides an enlargement including the sample absorption edge and the transitions of for the 0.1%–1.0%–5%Pr concentrations measured on 1 mm thick plates.
Excitation (at , 620, and 490 nm) and emission (at , 330, 450 nm) spectra of 1%Pr crystal measured on a 1 mm thick plate.
RL spectra of three PWO:Pr crystals in quantitative comparison with that of a BGO standard scintillator (equally shaped samples, 1 mm thick plates).
Photoluminescence decay of 1%Pr sample, , . The thick solid line is the convolution of the instrumental response (measured excitation pulse) and of the function . The inset shows the Pr-concentration dependence of the decay time in the 610 and 645 nm emission lines.
Spectrally unresolved scintillation decay of 1%Pr sample (30 mm long cylinder, excited by 511 keV photons of radioisotope).
TSL glow curves of all PWO:Pr samples after x-ray irradiation at RT. The signal increase above is due to black body radiation of the TSL heater.
