Abstract

We have employed Fourier-transform infrared spectroscopy in order to study the phase transitions and charge dynamics in vanadium oxide nanotubes with alternating organic and inorganic layers. The structural phase transitions accompanied by conformational changes in the organic layer were identified. Besides, a phase transition around 343 K from an insulator phase to a metal-like one that arises from electron delocalization was observed in the inorganic layers, manifesting an electron hopping oscillation between the V4+ and V5+ sites.
