In this research, Cu/Ag core-shell nanoparticles were synthesized by laser ablation in liquid using a nanosecond Nd:YAG laser. The synthesis of Cu/Ag core-shell nanoparticles by the laser ablation in liquid method was done in a single step by setting the process parameters at 450 mj/pulse energy, 1064 nm wavelength, 3 Hz frequency and 6 mm/s scanning speed in an acetone environment. Characterization of the synthesized nanoparticles using ultraviolet visible spectroscopy (UV-Vis), atomic absorption spectroscopy (AAS), dynamic light scattering (DLS), field emission scanning electron microscopy (FESEM), high resolution transmission electron microscopy (HRTEM), and
X-ray diffraction (XRD) were performed. The investigations confirmed that CACS nanoparticles had nanometric size, spherical morphology, and core-shell structure of pure copper/silver.
