- Abstract
- This study examined the preparation of monoclinic beta-Ga2O3 nanoparticles using liquid phase precursor synthesis with a liquid precursor and cellulose powder. The growth of beta-Ga2O3 nanoparticles and its structural properties were studied at various temperatures using X-ray diffraction, field emission scanning electron microscopy, transmission electron microscopy. The beta-Ga2O3 nanoparticles were synthesized at temperatures over 600 degrees C. The beta-Ga2O3 nanoparticles at 800 degrees C are single-crystalline monoclinic beta-Ga2O3 nanoparticles with a size of approximately 10-40 nm. The photoluminescence spectrum under excitation at 325 nm revealed blue emission, which was assigned to vacancies in beta-Ga2O3. (C) 2009 Elsevier B.V. All rights reserved.
