Abstract
Potassium nitrate (KNO3) and ammonium chloride (NH4Cl) flux were added during the combustion synthesis of Y2SiO5:Dy3+ (9 mol %) nanophosphors, which influenced its structure, morphology and thermoluminescent properties. Reduction in the crystallite size to ~ 7 nm observed using XRD analysis. Surface morphology enhanced in terms of its texture. Thermoluminescence analysis of the prepared phosphors irradiated with gamma dose over a range of 500 Gy – 4 KGy at a constant heating rate 3 ºC s–1 have been carried out. Kinetic parameters were evaluated by Chens method and activation energy was found to be 1.01-1.3 eV. Flux addition resulted in creation of large number of charge carriers and hence the material become the potential for dosimetry applications.
