Tailoring of Band Gap in Manganese doped Sodium Hexa-titanate

Abstract

Pure and Manganese doped Sodium Hexa-titanate (Na2 Ti6 O13) were synthesized using solid state reaction method. X-ray diffraction pattern reveals single phase and exhibit monoclinic structure of pure and doped samples. Morphologies of all synthesized materials have been studied using SEM. Absorption spectra of these samples have also been recorded and the same have been used to calculate the energy band gap using Tauc relation. The band gap lies in the range 3.71eV to 4.05 eV.
