Corresponding studies were conducted to obtain UV bands prohibited direct and indirect energy for this compound, which values are in 1.74 eV and 0.22 eV, in addition, there is a peak at 275 nm showing a high absorption in the ultraviolet region. HRTEM studies were performed to elucidate the crystal structure of the compound, finding characteristic values of 3.4 Å and 4.4 Å for an orthorhombic structure and stoichiometry of Co9Se8. FTIR confirms the existence of Co9Se8 nanoparticles and the study is complemented by RAMAN acquiring characteristic peaks for the synthesized compound. Finally, a study was conducted by XPS gaining characteristic peaks corresponding to CoSe.
