摘要: The nonlinear optical absorption of gold nanoparticles dispersed in polyvinyl alcohol (Au:PVA) is investigated using open aperture Z-scan technique. Au:PVA nanocomposite material synthesized by chemical method. characterization the done UV/Vis spectroscopy, transmission electron microscopy and X-ray diffractometry (XRD). It observed that nature depends on excitation wavelength. limiting capability sample also demonstrated at a wavelength 532 nm.
