Abstract
Y2O3:Eu3+ phosphor is one of the most promising oxide-based red phosphors. It is being studied since long time because of its efficient luminescence under ultraviolet (UV) and cathode-ray excitation. Y2O3: Eu3+ show luminescent properties and emits red light at a wavelength of 611 nm and was found to be suitable for many display devices. The present study focuses on the preparation, characterization and structural properties of Eu+3 doped Y2O3 nanoparticles obtained by co-precipitation method. The synthesized particles were characterized by X-ray diffraction (XRD), UV visible spectroscopy, Transmission electron microscopy (TEM) and Photoluminescence. All the powders were well crystallized spherical particles with average crystallite size of 85nm. An optimum concentration of 5 mol% Eu3+ doping exhibited maximum optical properties.
