“…Recently, the synthesis of nanometer-sized particles of metals, semiconductors and metal oxides has been investigated extensively because of their novel electrical, optical, magnetic, and chemical properties. Composites formed by metal ions or nano-clusters embedded in ceramics or glasses have recently attracted much attention as promising materials for applications in optoelectronics [1], separation membranes [2]. The synthesis of nanoparticles and control of their properties are important in many critical areas of modern technology such as catalysis, ceramic processing, solar energy conversion, pharmaceutics, and photography.…”
