Abstract: Thin Films Laboratory, Materials Physics Division, School of Advanced Sciences, VIT University, Vellore-632 014, Tamilnadu, India E-mail : [email protected] Centre for Excellence in Nano Materials, School of Advanced Sciences, VIT University, Vellore-632 014, Tamilnadu, India Nitrogen doped ternary metal oxide ZnTiO3 was synthesized by organic precursor method. Metal benzoate dihydrazinate complexes were prepared by a simple in situ chemical method. The formed metal benzoate dihydrazinate complexes were decomposed at different temperatures to yield the corresponding metal oxides. The samples were characterized by FT-IR, TGA and DSC, powder XRD, DRS, SEM and EDAX. Thermal analysis (TGA and DSC) revealed the decomposition path of the metal benzoate dihydrazinate complexes. XRD analysis confirms the polycrystalline nature of samples with pure phase formation. SEM analysis shows that the formed metal oxide powders are spherical particles. EDX confirmed the presence of 7.5 wt.% of nitrogen in the cubic phase ZnTiO3 . The optical studies were carried by recording diffuse reflectance spectra. Using Tauc’s relation (αhν)n = A(hν– Eg ) optical bandgap for nitrogen doped ZnTiO3 was found to be 3.91 eV.
