Hybrid Materials Of C₆₀ In Situ Decorating Metal Nanoclusters Prepared Successively By Pulsed Laser Ablation

In this article, 8 hybrid materials (M/C₆₀) formed by C₆₀ decorating surface of metal nanoclusters was prepared through pulsed laser ablation at the interface between metal solid target and a flowing fullerene solution of hexane and three of them was choosed to undertake a further study. UV-Vis, Energy dispersive spectroscopy, Element analysis, TG-DSC or TG-DTA indentify that surface of metal nanoclusters was decorated by C₆₀; TEM results indicate that original particles being as large as the size of clusters soon aggregate to nano particles when they were prodused by pulsed laser ablation because of their large specific surface. XRD results reveal that the diffraction peaks of the samples have lower value and broader width than pristine metal powders, indicating that surface of metal nanoclusters is decorated by amorphous material. Fluorescence intensity of metal nanoclusters increases due to the introduction of C₆₀, revealing that surface of these particles decorated by C₆₀ result in increasing electron concentration or extending delocalization range in them. Magnetism tested by VSM indicates that high temperature, high pressure and very rapidly cooled microarea in the method of PLA/ISFL are of importance in affecting the magnetic property of the hybrid materials.
