| Abstract: | Nanocomposites of Ni-Zn with copolymer matrix of aniline and formaldehyde in presence of varying concentrations of zinc ions
have been studied at room temperature and normal pressure. The energy band gap of these materials are determined by reflection
spectra in the wavelength range 400–850 nm by spectrophotometer at room temperature. From the analysis of reflection spectra,
nanocomposites of copolymer of aniline and formaldehyde with Ni1-xZnxFe2O4 (x = 0.0, 0.2, 0.4, 0.6, 0.8 and 10) have been found to have direct band gaps ranging from 1.50–1.66 eV. |
