Nanometer-sized Au particles were dispersed in Eu3+-doped amorphous spheres (Au-ES particles) which were synthesized by sol-gel and ion-exchange method. Au nano-particles were obtained as a single crystal at room temperature. Reduction of HAuCl4 combined with oxidation of C2H5OH occurred to form Au nano-particles. Au nano-particles dispersed in Au-ES particles showed surface plasmon absorption.
