Abstract: This paper reports a study of vibrational, structural and morphological properties of molybdenum oxide nanoribbons. Temperature-dependent Raman spectroscopy measurements in MoO 3 nanoribbons revealed morphological changes in the 150-350 °C temperature range. No structural phase transitions were observed, thus showing that the orthorhombic phase is stable from room temperature (nanoribbons) up to 650°C (bulk-like phase) where large plates have been formed by the coalescence of the nanoribbons. The interpretation of temperature-dependent Raman data (wavenumber and linewidths) is supported by scanning electron microscopy that is used to directly probe the morphological changes in MoO 3 samples. The observed phenomena in the Raman data for MoO 3 nanoribbons can be applied to other nanomaterials. Copyright © 2012 John Wiley & Sons, Ltd.
