 In this paper, structural and optical properties of copper (II) oxide nanoparticles, synthesized by pulsed laser ablation in liquid, have been investigated. Nanoparticles have been synthesized using ablation of pure copper in 10 vol% hydrogen peroxide solution, as an oxidizing media, using the fundamental wavelength (1064 nm) of a pulsed Ce:Nd:YAG laser with 10 ns pulse duration operated at a repetition rate of 10 Hz and laser pulse energy of 350 mJ/pulse. The ablation time was 30 minutes. Phase and crystalline structure of the sample were studied with X-ray diffraction (XRD), Fourier transform infrared (FTIR) and Raman spectroscopy. XRD pattern indicates that the product material is in two phases (Cu/CuO). FTIR and Raman spectra confirm the formation of CuO nanoparticles. Field emission scanning electron microscopy (FESEM) image of the sample shows synthesis of flake-like nanostructures. The UV-Vis absorption investigation shows that the synthesized material has a band gap of about 2.2 eV. The visible band gap energy makes the product material an ideal photocatalyst to harvest solar radiation for various applications.

Keywords: Laser ablation, Ce: Nd: YAG, Copper Oxide (II), Hydrogen peroxide
