In this research, the preparation of thin films was done by using the Pulsed Laser Deposition technique, where the measurements studied of structure, morphological and optical properties, including (XRD) of Ag/rGO and Ag/rGO/TiO2 films within pulsed energy varied from 600 to 1000mJ for each sample that deposited upon the substrate. At (XRD) pattern, the Ag peaks are more intense compared to the rGO peaks because the amount of rGO deposit particles is lower. Moreover, at Ag/rGO/TiO2 the peaks have being decreased along with the incensement of energy. (FESEM) it can be seen that as the pulse energy increases, the amount of deposit particles increases, confirming the formation of Ag/rGO and Ag/rGO/TiO2. The EDX results have proved the consistency of the films upon the silicon substrate as a result of high pulse energy that leads to more particles to deposits, (UV) Absorption Spectroscopy shows the sharper peak for Ag/rGO films which appears at 417nm have blue shift as energy pulse increased from 600 to 1000mJ, that proved the synthesis for Ag/rGO. However, the absorption peaks for (Ag/rGO/TiO2) are broader, a more intense peak was around 400nm with pulse energy 1000mJ, and a blue-shift has been observed overall film layer which confirms the consistency for the Ag/rGO/TiO2 multilayer thin films.
