Abstract
Europium doped cerium oxide particles of 10 nm were synthesized by room temperature chemical precipitation technique and annealed at 500 and 900 C to study its effect on luminescence. X-ray photoelectron spectroscopic result shows an increase in Ce(3+) concentration from 20% to 23% on Eu doping but decreases to 8% on annealing. Raman studies show a progressive blueshift from 461 to 464 cm(-1) due to local symmetry ordering with temperature. Emission intensity varies with the wavelength of excitation and observed transitions indicate the presence of Eu(3+) in different symmetry environments. (C) 2008 American Institute of Physics.
