Platinum (Pt) nanoparticles were prepared in solutions of ethanol and TSC (trisodium citrateNa3C6H5O7.nH2O) in water by laser ablation method using Nd:YAG laser. The role of laser ftuence, laser wavelength and concentration of surfactant liquids in laser ablation process were investigated. The morphology, size distribution and optical properties of the Pt nanoparticles (NPs) were observed by transmission electron microscopy (TEM), UV-vis spectrometer and xray diffraction measurements. The average diameter of Pt NPs prepared in ethanol and TSC solutions ranges around 7-9 nm and 10-12 nm, respectively. The results showed advantages of the laser ablation method.
