| Abstract | Nanocrystals of wide band gap materials (GaN and In2O3 were synthesized by sequential ion implantation in dielectric substrates, followed by thermal annealing of the samples. Transmission electron microscopy, extended X-ray absorption fine structure spectroscopy and grazing incidence X-ray diffraction analyses confirmed the formation of GaN and In2O3 crystalline nanoparticles. Blue shift of the near-edge photoluminescence (PL) band (quantum confinement effect) was observed for GaN nanocrystals. A strong PL band peaked at 3.35 eV was detected upon excitation of In2O3 nanocrystals at 5.20 eV. © 2002 Elsevier Science B.V. All rights reserved. |
