| dc.description | In the present project copper sulfide nanoparticles were prepared by a chemical reaction between copper (II) complexes of long chained n-alkyldithiocarbamate (6, 12 and 18 carbon atoms) and sodium borohydride. The nanoparticles were characterized by infrared spectroscopy, X-ray powder diffraction, scanning electron microscopy, transmission electron microscopy, termogravimetric analysis and differential scanning calorimetry. In addition, the samples were characterized by diffuse reflectance spectroscopy in order to calculate the optical band gap energy of every case using the Kubelka-Munk theory. The results obtained demonstrate that the nanoparticles size average is around 10.0 nm distributed throughout the dithiocarbamate matrix. These particles present three different copper sulfide phases (covellite, digenite and chalcocite). Finally, the optical band gap energy is 3.4 eV in average. | - |
