Synthesis and Characterization of Bi@Bi2O3 Nanoparticles
碩士 === 國立東華大學 === 物理學系 === 107 === Bismuth (Bi) thin films and nanoparticles were synthesized using Pulsed Laser Deposition (PLD) technique. Bismuth thin films and nanoparticles were synthesized at various substrate temperature of 25, 50, 75, 100, 125, 150, 175, 200, 225 and 250 °C. The properties o...

The surfaces of the Bi thin films and nanoparticles were oxidized in atmospheric pressure and at room temperature. The oxidized surfaces of the nanoparticles and thin films were studied using XPS. The Raman spectroscopy and XRD studies confirm that the synthesized thin films and nanoparticles are of Bi metal of hexagonal crystal structure. Yuan- Ron Ma 馬遠榮 2019 學位論文 ; thesis 56 en_US |
