Fabrication and Characterization of Ti and TiO2 Nanoparticles by Pulsed Wire Evaporation and Transmission Electron Microscopy

초록

Ti and TiO2 nano-sized particles were fabricated by pulsed wire evaporation (PWE) and characterized. The differences in the size and shape distribution according to the charging voltage, V-0 (2.8 to 6.5 kV), were investigated. From the high-resolution transmission electron microscopy (TEM) images, a new phase of face-centered cubic Ti nanoparticles was observed. Electron-energy loss spectroscopy coupled with high-resolution TEM revealed three phases in TiO2 nanoparticles: anatase, rutile, and brookite. PWE methods and these observations highlight the potential of developing novel nanoparticles with unprecedented structures and/or properties.
