Abstract

In this presentation, we described a study on preparation and microstructure of Au (Ru) nano-particles embedded in SiO2 matrices, which were prepared as advanced display materials by using Sol-gel method. Both microstructure and composition of these micro/nano-particles composites were characterized by HRTEM (high resolution transmission electron microscope), EMP (electron microprobe) and nano-probe EDS (energy dispersive X-ray spectroscopy). Experimental results showed that the products have multi-levels in structure like nebulae. The aggregation of Au/Ru nano-particles can be extremely diminished by using SiO2 micro-particles as matrices. Distortions of the atomic lattices of Au and Ru nano-crystallites were often observed in the surface of these nano-particles. Moreover, nano-EDS measurements revealed that Au and Ru nano-particles are always separately embedded in SiO2 matrices, no alloy of them is observed.
