Formation of the Metallic Nanoclusters in Glasses

Formation of metallic nanoclusters in glasses has drawn the attention of researchers as these composite glasses promise well for the fabrication of photonic and all optical switching devices due to their linear or non-linear optical properties.In this paper,the synthesis techniques for formation of metallic nanoclusters in glasses were presented.Glasses containing metallic nanoclusters might be synthesized by a variety of methods.The traditional melt-quenching method,direct metal-ion implantation followed by high temperature annealing,ion-exchanged method,photo-irradiation by high temperature annealing method,sol-gel method,etc.are,for example,some of the successful methods for preparation of these glasses.The photo-irradiation by high temperature annealing method was found to be a simple technique.
