Abstract

CoPt(Ag) nanoparticles have been synthesized by high temperature polyol reduction of cobalt, platinum and silver reagents. It was found that by varying the reaction conditions, particles with different sizes and shapes can be obtained. The as-made particles were well dispersed in hydrocarbon solvents, and self-assembled particle arrays were formed when deposited on Si substrates for magnetic measurements and on carbon coated grids for transmission electron microscopy.
