    • Abstract

       

      The present study reports the structure and optical properties of Sr-doped NdFeO3 nanoparticles synthesized by the simple co-precipitation method without the introduction of surfactants. Structural phase formation of the crystal exhibited orthorhombic planes of all samples (Nd1-xSrxFeO3; x = 0.1, 0.2, and 0.3).The average crystal size and unit cell volume are increasing with a dopant (DXRD = 28 ± 3–35±3 nm;V = 236.52–238.07 A˚3). The obtained Sr-doped NdFeO3 nanoparticles have higher absorption in the visibleregion (k = 400–800 nm) than in the UV range (k = 200–400 nm) and the band gap value(Eg = 0.87–1.06 eV) is much lower than similar rare-earth perovskite series such as NdFe1-xCoxO3, Y1-xSmxFeO3, HoFe1-xNixO3, LaFe1-xTixO3, and Y1-xGdxFe1-xCoyO3 synthesized by different methods.The excellent optical properties of Sr-doped NdFeO3 nanomaterials give them great potential for applications related to optics.

      Sr-doped NdFeO3 nanoparticles were synthesized by the simple co-precipitation method. The obtained Sr-doped NdFeO3 nanoparicles have higher absorption in the visible region than in the UV range and the band gap value (Eg- = 0.87–1.06 eV) is much lower than similar rare-earth perovskites synthesized by different methods.
