Abstract: A novel nano-cobalt/ethanol sol was firstly obtained by pulsed laser ablation on the interface of solid and flowing-liquid. TEM results show that nano-cobalt particles size is about 30 nm. Electronic diffraction and XRD analysis both indicate that the nano-cobalt is non-crystalline. It was found that the stretching vibration of associating hydroxyl(γOH) and the deformation vibration of C-H in ethanol are strengthened, but stretching vibration of γC-O in primary hydroxyl of ethanol is restrained through the FTIR spectrum. The UV-Vis results show that there are one strong absorption peak at 231.99 nm due to primary nano-cobalt particles and two medium absorption peaks at 273.00 and 308.56 nm due to quantum confine effect.

Key words: Cobalt/etanol sol, Nano-material, Pulsed laser ablation
