Study the effect of the aqueous media on the properties of produced copper nanoparticles colloidal by using laser ablation technique

الملخص EN

This paper reports our recent studies on the generation of Cu NPs by ablation of metal targets using Q-switch Nd-YAG laser with Second Harmonic Generation(S.H.G) (λ=532nm) immersed in different aqueous media( Double Disteled Deionised Water (DDDW) and 1-Propanol) .Higher productivity and Smallest size have been produced by using 1-propanol solution compared to DDDW, which indicated that the productivity and NPs size were affected by the solution type.

Optical properties measurements showed indirect optical energy gap of the produced Cu nanoparticle (3.717 and 4.887) eV , when the solution type change from DDDW to 1-Propanol respectively.

The Surface topography studied by Atomic Force Microscopy, and shape were measured by using Scanning Electron Microscope SEM shows spherical shape while the composing of the prepared nanoparticle were determined by X-ray diffraction ,UV-Visible spectroscopy has been employed for the optical properties measurements
