Raman spectroscopic studies are performed to probe the stress along the length of a bent ZnO nanowire. The zone‐centre E2high optical phonon shows a systematic red shift as the junction point of the two arms of the nanowire is approached. The mechanism of the red shift is discussed on the basis of the tensile strain. From the red shift of the phonon peak position, the strain at different regions on...
Composite vanadium oxide (VOx)‐based fibres were synthesised by the electro‐spinning method combined with conventional sol–gel processing using polyvinyl acetate (PVAc) as a polymeric binder and vanadium oxytriisopropoxide as a vanadium oxide precursor. The microstructure and composition of as‐spun and calcined (300–500 °C) VOx–PVAc fibres were systematically investigated by scanning electron microscopy,...
