| Abstract: | Nanoparticles of
NiFe2O4 have been synthesized by chemical
co-precipitation method. X-ray diffraction pattern confirms the formation of
single-phase cubic spinel structure and the lattice constant is 8.2 Å. The
energy band gap measurements of nanoparticles of Ni ferrite in pellet form have
been carried out by reflection spectra using double beam spectrophotometer. A
pellet of nanoparticle ferrite was made under a load of 10 tons. From the
analysis of reflection spectra, nanocrystalline Ni ferrite have been found to
have energy band gap of 2.5 eV at room temperature. |
