摘要
The family of copper selenides has attracted significant interest due to its many phases and a variety of compounds. Many studies confirm the applicability of copper selenides as important solar cell materials. A simple sonochemical method was developed to synthesize various copper selenides in aqueous solutions, using Cu(CH3COO)(2) as copper source and Na2SeSO3, elemental Se and selenourea as selenium sources. X-ray powder diffraction (XRD), transmission electron microscopy (TEM) and chemical analysis show that different copper selenides with crystallite sizes between 9 and 28 nm were obtained in high yield.
