How to obtain cobalt telluride through a versatile method, based on an ion exchange by aqueous chemical reaction, conformer by rongalite, sodium hydroxide and cobalt chloride. In the UV-vis characterization, a direct and indirect band gap interval of 2.32 eV and 2.04 eV was determined. In the optical absorption, two peaks are observed, one at 270 nm and 411 nm, wich correspond to this material. The FTIR study for cobalt telluride, absorption peaks are seen at 828 cm -1 corresponding to the O-Te group, while the peak of 621 cm -1 can be attributed to Te-O and finally the peak at 524 cm -1 corresponds to the vibration of Co-O links. The RAMAN spectro obtained, shows peaks of 460, 660 and 984 cm -1 corresponding to cobalt tellurium.
