Magnesium oxide nanocrystals via thermal decomposition of magnesium oxalate

The present work reports the synthesis of magnesium oxide (MgO) nanocrystals via a thermal decomposition route and the study of physicochemical properties of products The MgO nanocrystals were prepared from magnesium oxalate powders as precursor Transmission electron microscopy (TEM) analysis demonstrated MgO nanocrystals with an average diameter of about 20-25 nm The products were characterized by X-ray diffraction (XRD) transmission electron microscopy (TEM) selected area electronic diffraction (SAED) and Fourier transform infrared (FT-IR) spectroscopy Optical absorption and photoluminescence emission properties of MgO nanocrystals were investigated (C) 2010 Elsevier Ltd All rights reserved
