Rapid synthesis of pure and narrowly distributed Eu doped ZnO nanoparticles by solution combustion method
Résumé
Pure ZnO Eu(3+) nanoparticles (similar to 50 nm) were prepared by a solution combustion method ZnO and Eu(2)O(3) were used as starting materials and dissolved in nitric acid Citric acid was used as a fuel The reaction mixture was heated at 350 C resulting into a rapid exothermic reaction yielding pure nanopowders The atomic weight concentration of Eu3+ doped in ZnO was 20% Transmission electron microscopy (TEM) was used to study the particle size and morphology The nanopowders were characterized for phase composition using X ray diffractrometry (XRD) Particle size distribution (PSD) analysis of ZnO Eu(3+) showed particlesizes ranging from 30 to 80 nm The photoluminescence emission spectra of ZnO Eu(3+) nanostructures showed a strong band emission around 618 nm when excited with 515 nm wavelength (C) 2010 Elsevier B V All rights reserved
