AB - The current study used a Pulsed laser deposition (PLD) method to create Multilayer Ag/GO/TiO2 nanostructures. Two methods of preparation were used, the first was the co-precipitation for preparation of silver nanoparticles and titanium dioxide nanoparticles, and the second method was microwave assisted combustion that prepared the Graphene NPs. The measurements have been studied, such as X-ray diffraction (XRD) confirming the spherical crystalline structure of the Ag nanoparticles, TiO2 and GO nanoparticles, the samples resulting from this methods were pressed for the purpose of converting them into pellet used in the preparation of thin films, where these were prepared by laser deposition method and measurements were studied for them, such as (XRD) Ag thin films at 200°C and 300°C with varied pulsed energy deposited onto the glass substrate separately. We noted that as the pulsed energy increasing from 400 mJ/p (pulse) to 1000 mJ/p same of peaks disappeared, field emission scanning microscopic (FESEM) for sliver nanoparticles a very pleasant spherical particle with average crystallite size is 37.18 nm, observes for GO as wrinkled paper-like with crystallite average size 8.04 nm, TiO2 observed as densely aggregated in the form of big cluster with crystallite average size 18.8 nm, Ultra violet-Visible-Near infrared (UV–VIS-NIR) Absorption Spectroscopy silver nanoparticles films that prepared in 200°C (Ag200) and 300°C (Ag300) at 448 nm and 435 nm respectively, the broadened peak with low absorption is due to increasing in silver particle size. There a red shift at 527 nm and 457 nm, the higher absorption peak was observing at 453 nm. It is found that the surface morphology of the multilayer depends on the conditions of fabrication. Thus, the ultimate structure’s size and shape can possibly be controlled by laser energy changes.
