dc.description.abstract Novel optical and electrical properties of newly synthesized nano-wires of monoclinic WO3 and nano-belts of rutile VO2 have been investigated by Raman spectroscopy and thermochromism studies respectively. Phonon confinement is observed in the WO3 nano-wires and the previously modified Richter equation is fitted to the experimental Raman spectroscopy data to obtain the optical phonon dispersion relations for the 713 cm–1 branch and the 808 cm–1 branch of WO3 phonon spectra for the first time. Electrical measurements on the VO2 nano-belts at varying temperature reveal an enhanced hysteresis width of about 83 °C surpassing previously reported values on the thermo-chromism studies on VO2. en
