(1− x )CuCo 2 O 4 / x MnS ( x  = 0, 0.25, 0.5) nanocomposite samples were formed using hydrothermal and thermolysis procedures. X-ray diffraction (XRD) phase analysis showed the formation of only CuCo 2 O 4  phase necessitating the inclusion of Mn and S ions into the CuCo 2 O 4  lattice. Fourier-transform infrared spectroscopy (FTIR) analyses confirmed the presence of Mn and S ions in the nanocomposite samples. Rietveld refinement method was applied to determine the cation distribution of the different ions between different sites. The cell parameter ( a ) has no fixed trend of change. The average crystallite size is almost the same for all samples with an average of 15 nm. The effect of insertion of Mn and S ions into the CuCo 2 O 4  on the diffused absorbance, extinction coefficient, refractive index, dielectric properties, and nonlinear optical parameters was discussed in detail. The pristine CuCo 2 O 4  nanoparticles have two direct optical band gaps (1.65, 2.74) eV which are decreased to (1.59, 2.56) and (1.58, 2.54) eV for the MnS content  x  = 0.25 and 0.5, respectively. The two indirect optical band gaps of pristine CuCo 2 O 4  changed irregularly as the MnS amount increased in the nanocomposite. The PL spectrum of CuCo 2 O 4  is shifted to higher wavelength in the visible region upon alloying with MnS. The photoluminescence (PL) intensity of the nanocomposite samples is smaller than that of CuCo 2 O 4  sample. The emitted PL colors depended on the amount of Mn and S ions in the CuCo 2 O 4  matrix.
