We report the band gap tunability of (1 - x)Na0.5Bi0.5TiO3-xBiMnO(3) (x = 0.00, 0.05, 0.10 and 0.15) ceramics by a solid-state reaction method. X-ray diffraction (XRD) analysis confirmed the phase formation of rhombohedral structure with the space group of R3c. Rietveld refinement of XRD data revealed that the structural symmetry as a function of x composition. Raman analysis exhibited the vibrational phonon frequencies associated with Bi-O, Na-O, and TiO6 octahedral vibrations. The realized band gap energy variations (3.35-2.53 eV) suggesting that the synthesized ceramics materials are promising for photovoltaic and photocatalytic applications.
