8 - Hydrothermal Synthesis and Crystal Growth of Fluorides, Sulfides, Tungstates, Molybdates, and Related Compounds (Coordinated Complex Crystals, Part II)

Abstract

In Chapter 8 we deal with fluorides, sulfides, tungstates, titanates, molybdates, tantalates, neobates, selenides, and related compounds. The synthesis of these compounds did not carry much geological significance in the past; hence, their synthesis began in the middle of the twentieth century. However, the interest was purely academic. Today, these compounds have a great technological significance. Although the synthesis of these compounds is being studied extensively worldwide, interest is more confined to the nanosize crystals rather than the bulk single crystals growth. Some of these coordinated complexes with reductions in the size and the establishment of core-shell structures carry special characteristics useful as sensors, quantum dots, imagers, semiconductors over a wide band gap region, and so on.
