Electrodeposition of Cu2O nanostructures with improved semiconductor properties

Abstract

In the present research, nanocomposites based on copper (I) oxide poly (1-vinyl-2-pyrolidone-co-itaconic acid) nanostructures (Cu 2 O/p(NVP-co-AI)) were synthesized by the electrodeposition method using the copolymer p(NVP-co-AI) as a stabilizing agent in the reduction of Cu +2 to Cu + . The chemical and physical properties of the nanostructures were characterized by techniques such as scanning electron microscopy, infrared (IR) spectroscopy, Raman and ultraviolet-visible spectrophotometry. The obtained nanostructures are mainly a mixture of agglomerated nanospheres with a diameter of approximately 78 to 91 nm, with an alternation of nanolaminar structures, composed of copper (I) oxide species. In the case of the Cu 2 O/p(NVP-co-AI) nanocomposite, it was observed a decrease in the carbonoxygen vibration links of the carbonyl groups in IR intensity for the polymer when it was dissolved in the electrolytic solution, which indicates that interactions are produced by the carbonyl groups with the Cu 2 O species. In addition, bandgap values of 1.80 and 1.63 eV were estimated by the Kubelka-Munk method for Cu 2 O and Cu 2 O/p(NVP-co-AI) samples, respectively.

In-Depth Study of Chemically Electrodeposited Cuprous Oxide (Cu2O) thin Films on ITO Glass

“…As a result, this method has received considerable attention for the deposition of metals and semiconductor materials [7][8][9]. The electrodeposition of p-type Cu2O thin films is usually performed in a basic electrolyte containing Cu 2+ ions and a chelating agent such as f lactic acid, citric acid, or tartaric acid to prevent Cu precipitation in basic conditions [10].…”
