Optical and Magnetic Properties of Co-V-doped TiO2 Synthesized via Chemical Route
摘要
TiO2 based Materials have captured the interest of researchers in the last few years because of their remarkable photocatalytic and semiconducting properties. This paper includes successful synthesis of Co-V-doped TiO2 (TCVO). Rietveld refinement was done to know the lattice parameter of TCVO. X-ray Photoelectron Spectroscopy (XPS) studies validate exact oxidation state of each element of TCVO. The morphology of TCVO was found to be polygonal and scattered. The purity of the compound was confirmed from Energy Dispersive spectroscopy (EDS) analysis. Average grain size and average particle size of TCVO was found to be 3.406 ± 0.5 μm and 2051 ± 120 nm. Optical band gap of TCVO was observed to be 1.94 eV. The cobalt and vanadium doped TiO2 exhibit presence of weak ferromagnetism and paramagnetic characteristics (MH curve) which was confirmed with the help of magnetic susceptibility (χ) versus temperature plot and blocking temperature (TB) of the synthesize materials estimated through Magnetization versus Temperature (MT) curve which was found to be 3.5 K.
