Abstract
The impact of laser wavelength on gold nanoparticle (Au NPs) creation is
accounted by the extraction of gold atoms from the gold specimen immersed in ethanol.
Pulsed Laser ablation in fluid procedure of the gold target was carried out by employing
Nd:YAG laser (nanosecond pulses). Characterization of accomplished gold NPs was
achieved by Atomic Force Microscopy AFM), X-Ray Diffraction (XRD) and UltravioletVisible (UV-VIS) absorption and transmission spectroscopy. The outcomes demonstrated
the attributes of the prepared NPs, contingent upon XRD, AFM. NPs gotten by 532 nm
laser have preferred properties over that accomplished by 1064 nm laser as indicated by
the highest values of intensity of shorter wavelengths
