Abstract

ABSTRACT: Pure and neodymium (Nd) substituted yttrium oxide nanoparticles were synthesized by the co-precipitation technique. The synthesized materials were annealed at 350°C, 500° C, 750° C and 1000° C using a muffle furnace at an open atmosphere. X-ray diffraction patterns, FTIR spectra and XPS spectra were recorded to study the structural variations. The morphology has been studied through high-resolution SEM images. The elemental analysis was carried out using energy-dispersive spectral analysis by X-rays. The particle sizes and crystalline nature of the annealed samples were studied by transmission electron microscopic images and their corresponding SAED patterns. The photoluminescence spectral analysis indicated that the pure, as well as Nd-substituted materials have emissions in the blue and green regions. It is also observed that the substitution of Nd has enhanced the emission in the blue region. Moreover, the photoluminescence of Nd-substituted Yttrium oxide has a significant variation with respect to annealing temperatures.
