X-RAY PHOTOELECTRON SPECTROSCOPY AND RAMAN STUDIES OF ZnO:Ce NANOCRYSTALS
Abstract
Cerium-doped ZnO nanopowders were synthesized using the simple refluxing technique. The synthesized samples were characterized by X-Ray diffraction, which confirmed their hexagonal structure. No additional peaks due to the interstitial incorporation or substitutions of Ce4+ ions into the ZnO lattice were observed. Ce 3d3/2 and 3d5/2 had well-separated orbits of ∆ = 18.26 eV. The observed spin-orbit splitting as well as the separation between 3d5/2 peaks by 16.47 eV were in good agreement with those reported. The presence of 917.85 eV also confirmed the presence of Ce4+ ions. Raman studies showed that for Ce-doped ZnO the nonpolar interaction E2H grew strong and had a dominant intensity.
