Summary
Scintillation materials are widely used in digital X-ray imaging applications, radiotherapy applications coupled with suitable photoreceptors.Gd2O2SO4 (GOS) scintillator doped with trivalent praseodymium (Pr 3+ ) presented high X-ray absorption properties and good spectral compatibility which were utilized extensively for imaging system of X-ray microscopy, soft X-ray phosphor screen for water window.In this study, GOS:0.01Pr3+ scintillation material was synthesized by unique sol-gel process which was not previously applied and its characterization properties were investigated.Structure and luminescence properties of GOS:Pr 3+ were optimized by utilizing X-ray diffraction, X-ray photoelectron spectroscopy, scanning electron microscopy, and luminescence spectroscopy.
