The objective of this study was to compare the illumination properties of halogen with a manganese cobalt (Mn-Co) composite material using a novel sol-gel method. The manganese and cobalt were doped using the sol-gel method to prepare the composite material. Gradual addition of ethanol was done to remove negative ions from the composite. The illumination characteristics of the Mn-Co composite material were evaluated using XRD (X-ray diffraction), SEM (Scanning electron microscope), and UV-Vis (Ultraviolet-Visible) testing methods. Two groups were selected for the investigation of the UV-Vis absorption spectrum: Group 1 – Halogen at the activation temperature of 1000 °C, and Group 2 – Mn-Co composite material at the peak activation temperature of 1000 °C. Each group consisted of 20 samples, determined based on a pretest power of 80%, a probability value of 0.05%, and a confidence interval (CI) of 95%. A complete of 2 specimens were divided into a pair of teams with G-power of 80. The research findings indicated that the particle size of the Mn-Co composite material increased with the rise in temperature, and the peak absorbance wavelength decreased with increasing particle size. The results revealed a statistically significant difference between the two groups, with a p-value of 0.000 (p < 0.05). The analysis focused on examining the crystal structure of the composite material, phase purity, and optical properties. The band gap (eV) (0.7370 mm³/sec) of Mn-Co nanoparticles mean was found to be 0.3568 mm³/sec, which is higher than that of normal illumination. This study concluded that the Mn-Co composite material provides enhanced illumination compared to halogen material, which only provides normal illumination. The sol-gel method allowed for the efficient doping of manganese and cobalt in the composite, leading to improved illumination properties. The findings from this research could have significant implications in the development of advanced lighting materials for various applications.
