Abstract

Vanadium substituted TiO<subscript>2</subscript> samples are prepared by modified sol-gel process. X-ray diffraction (XRD) pattern and Raman spectra for all the samples reveal pure tetragonal phases of TiO<subscript>2</subscript>. Rutile percentage calculated from XRD pattern and Raman spectra follow a similar trend and signify that vanadium substitution promotes phase transformation from anatase to rutile. Due to aliovalent V substitution, donor levels are formed in the bandgap which is responsible for bandgap reduction. [ABSTRACT FROM AUTHOR]
