Study of sulphur doped TiO2: Structural, morphological, optical and thermal properties
Titanium dioxide (TiO2) is a widely used transparent conducting oxide which has found many applications in solar cell devices. In the present study we have synthesized 0.75 sulphur doped TiO2 (S-TiO2) by ball milling technique and investigated their structural, topological, optical and thermal properties. The crystallization, strain and particle size have been analyzed by X-ray diffraction and reveals the formation of single phase structure corresponding to anatase phase of TiO2. AFM investigations reveal a homogeneous surface morphology. FTIR spectroscopy confirms the presence of sulphur bonding in the TiO2 crystal structure. Band gap was calculated from the absorption spectrum of S-TiO2 obtained using UV-visible spectrophotometer. The value of 3.07 eV obtained as band gap for S-TiO2 is less than that of of anatase TiO2 (3.2 eV) thus shows shifting towards the longer wavelength on sulphur doping. DTA-TGA measurements also corroborate that S-TiO2 crystallizes in the anatase phase.Titanium dioxide (TiO2) is a widely used transparent conducting oxide which has found many applications in solar cell devices.
