| Abstract: | Sols of copper clusters/n-hexane was prepared through pulsed laser ablation at the interface between copper solid target and a flowing liquid of hexane. Spectrum of UV-Vis shows that sols of copper clusters/n-hexane have four absorption peaks at 199,215,219 and 226 nm. Fluorescence indicates that the sols have two excitation peaks at 308 nm and 273 rim, and two emission peaks at 370 nm and 385 nm ;TEM reveals that the content of nanoparticles decreases with the increase of particle diameter, and the average diameter is 14.1 nm. |
