摘要：
High-purity platinum nanoparticles (PtNPs) has been successfully synthesized in a pure water by using laser ablation method utilizing low-power neodymium yttrium aluminium garnet (Nd:YAG) laser at fundamental wavelength. Experimentally, pulse laser beam (Nd: YAG laser, 1064 nm, 7 ns, 30 mj) was directed and focused onto a high-purity platinum sheet (99.9%), which was placed into a pure liquid of deionized water, to produce PtNPs colloid. The morphology, size distribution and optical properties of the Pt nanoparticles (PtNPs) were observed by scanning electron microscope (SEM) and UV-vis spectrometer. The average diameter of Pt NPs prepared in 10 HZ and 15 Hz ranges around 8 nm and 9 inn, respectively. Dark-yellow color colloid containing high-purity PtPs was successfully produced.
