This study reports the synthesis of pure double perovskite Eu2NiMnO6 in nano ceramic forms using solvothermal and sol-gel routes without europium and magnesium nitrate. X-ray powder diffraction reveals a monoclinic P21/n structure and the particle size is determined to be around 43 and 59 nm. The chemical, homogeneous, and optical properties of nanoparticles are confirmed by SEM, UV-vis absorbance, and FTIR spectra. The calculated energy band gap of Eu2NiMnO6 using density-functional theory is close to the experimental value.
We reported on the synthesis of the pure double perovskite Eu2NiMnO6 in nano ceramic forms by two different methods solvotermal and sol-gel routes without europium and magnesium nitrate. Room temperature X-ray powder diffraction study of the compound revealed a monoclinic P21/n structure. The particle size was determined by the Williamson-Hall and Scherrer formula and found around 43 and 59 nm for the average size. The chemical, homogeneous and optical properties of nanoparticles were confirmed by SEM, UV-vis absorbance and FTIR spectra. The Eu2NiMnO6 has an energy band gap 1.32 eV determined by Heyd-Scuseria Ernzerhof (HSE06) from density-functional theory (DFT) calculations close to the value found experimentally 1.01 eV.
