Synthesis and Characterization of Gd₂O₂SO₄:Pr³⁺ Scintillation Material Produced by Sol-Gel Process for Digital Imaging System

Abstract

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:0.01Pr 3+ 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.

Assessing of photoluminescence and structural properties of Dy+3 doped cadmium tantalate phosphor

“…Hence, rare earth (RE 3+ ) doped materials have wide range of applications in the field of solid state lighting, display, and laser technologies. Moreover, in recent years, white light emitting diodes (W-LEDs) have been targeted as next generation solid state lighting sources due to the advantages of energy saving, high efficiency, long lifetime, reliability and environmentally friendly properties [8][9][10][11][12][13][14][15][16][17][18]. Trivalent dysprosium (Dy 3+ ) doped phosphors are of great attention due to white light emission property.…”
