Objectives: In this article Zinc doped Sodium Hexa-titanate ceramic materials were prepared for investigating of optical behaviors. Methods and Analysis: Pure and Zinc doped Sodium Hexa-titanate (Na2 Ti6 O13) ceramic materials have been synthesized using solid state route method, by adding sodium carbonate and titanium dioxide in a proper ratio and passes through different process. Structure and phase of all synthesized ceramic materials were analyzed using X-ray diffraction, and found single phase and monoclinic structure of pure and zinc doped samples. Morphology of all synthesized materials has been studied using scanning electron microscopy. Absorption spectra of these Hexa-titanate samples have also been recorded. Findings: The Crystalline size of synthesized samples was calculated with Debye-Scherrer equation, as well as the energy band gaps have been calculated using Tauc relation with respect to absorption wavelength. Application: The energy band gap has been reduced by doping ZnO from 3.780eV to 2.779eV. These narrower band gaps can be used in different infrared and thermoelectric sensors.
