In this work, orthoferrite NdFeO3 nanomaterials with particle sizes 20-40 nm have been successfully synthesized via a simple co-precipitation method through the hydrolysis of Nd (III) and Fe cations in hot water 5% NaOH as precipitating agent. Single-phase was generated after calcination as-prepared powder at 700, 800, 900 °C for 1 hour. The UV-Vis spectra room temperature presented strong abso...
