Resumen

This paper presents a new method for obtaining cobalt selenide. 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.
