Pure manganese titanate (MnTiO 3 ) nanopowders have been synthesised by stearic acid gel method. Structural investigations by X-ray diffraction and scanning electron microscopy confirm that the synthesised material is MnTiO 3 with rhombohedral crystal structure. Transmission electron microscopy showed that the particle sizes are in the range of 22-30 nm. The formation of MnTiO 3 is further supported by the FT-IR and energy dispersive X-ray spectra. An optical band gap of 3.18 eV is determined for MnTiO 3 nanopowders from the UV-vis absorption spectrum. A broad emission band with maximum intensity at around 487 nm is observed in the photoluminescence spectra of MnTiO 3 nanopowders at room temperature depicting the blue emission, which can be attributed to the
