Metallic copper nano particles are synthesized with citric acid and CTAB (cetyltrimethylammonium bromide) as surfactant and chlorides as precursors. The particle size and surface morphology are analyzed by High Resolution Transmission Electron Microscopy. The average size of the nano particle is found to be 3 - 10 nm. The optical absorption characteristics are done by UV-Visible spectrophotometer. From the Tauc plots, the energyband gaps are calculated and because of their smaller size the particles have much higher band gap than the bulk material. The energyband gap is changed from 3.67 eV to 4.27 eV in citric acidcoatedcopperquantum dots and 4.17 eV to 4.52 eV in CTAB coatedcopperquantum dots.
