Study optical and structural properties of copper oxide nanoparticles prepared by pulse laser ablation technology in (LC/MS) water

Copper oxide nanoparticles (CuO NPs) were prepared by pulse laser (Nd: YAG Qswitch, λ=1064nm, frequency=6 Hz) ablation technology for copper target in height purity water type liquid chromatography / mass spectrometry (LC/MS), at energy (200) mJ and different pulses (100, 200, 300, 400) pulse to formation colloidal solution. Found surface Plasmon resonance (SPR) at (200) mJ and (100) pulses is (625) nm, when increases in pulses the (SPR) is nearly constant. The indirect optical energy gab for these solution (4, 2.7, 2.75, 2.5) respectively, with the increase in number of pulses, the energy gap by using Fluorescence Spectrophotometer (3.543) eV.
