Synthesis of paramelaconite nanoparticles by laser ablation

Paramelaconite nanoparticles have been obtained by laser ablation from a copper target in propanol. Copper oxide nanoparticles were characterized by high resolution transmission electron microscopy (HR-TEM), ultraviolet-visible (UV-Vis) spectroscopy, and X-ray diffraction. HR-TEM images demonstrated particle size in the range of 60–70 nm. It is observed that nanoparticle size depends on the wavelength and intensity of the laser. The results show that the stability of paramelaconite is affected by the high temperatures and oxidizing atmosphere, leading to a mixed phase of tenorite and paramelaconite.
