Synthesis of copper nano/microparticles via thermal decomposition and their conversion to copper oxide film

Copper nano/microparticles were synthesized in octadecene at 290 °C by thermal decomposition method. acetate monohydrate, stearic acid, and 1-octadecanol used as copper precursor, capping mild reducing agents, respectively, the synthesis. Borosilicate glass substrates submerged into reaction solution during synthesis coated nano/ microparticles. Thermal coating techniques combined this study. thoroughly characterised via X-ray powder diffraction, photoelectron, Raman, attenuated total reflectance-Fourier transform infrared spectroscopies, scanning transmission electron microscopies. The average minimum Feret?s diameter of these particles was measured ~87 ± 19 nm. converted to oxide microparticles applying heat treatment 250 °C. phase composition determined reference intensity ratio analysis. energy gap ~2.33 eV using Tauc?s Their band PL emission observed ~2.15 eV.
