Calcium Manganite (CaMnO3) and Strontium Manganite (SrMnO3) nanostructured perovskite oxides wereprepared by cost effective and size controllable hydrothermal method at pH 9.2 with and without chelating agent. The asprepared samples were annealed under air at 800°C. Single phase and crystalline material was observed by X-Raydiffraction and the average crystallite size was in the range of 40-60 nm. SEM Micrograph showed the homogeneouslydispersed nanomaterials without agglomeration. Strong doublet peak around 550 cm -1confirmed the formation of perovskiteoxides by Fourier Transform Infrared Spectroscopy. The absorption peaks were observed by using UV- Visible spectroscopyand the band gap was estimated from Tauc’s relation. The indirect band gap increased for the chelating agent used samplewhere it influenced by the crystallite size of the nanomaterials.
