This book primarily covers the fundamental science, synthesis, characterization, optoelectronic properties, and applications of metal oxide nanomaterials. It discusses the basic aspects of synthetic procedures and fabrication technologies, explains the related experimental techniques and also elaborates on the current status of nanostructured oxide materials and related devices. Two major aspects of metal oxide nanostructures – their optical and electrical properties – are described in detail. The first five chapters focus on the optical characteristics of semiconducting materials, especially metal oxides at the nanoscale. The following five chapters discuss the electrical properties observed in metal oxide-based semiconductors and the status quo of device-level developments in a variety of applications such as sensors, transistors, dilute magnetic semiconductors, and dielectric materials. The basic science and mechanism behind the optoelectronic phenomena are explained in detail, to aid readers interested in the structure–property symbiosis in semiconducting nanomaterials. In short, the book offers a valuable reference guide for researchers and academics in the areas of material science and semiconductor technology, especially nanophotonics and electronics.

Crystals of an incongruent-melting compound, Ba3MgSi2O8, were grown by the flux method and its structure was determined by single crystal X-ray diffraction methods. Ba3MgSi2O8 crystallizes in trigonal space group P-3[bar]m1 with a = 5.6123(3) Å, c = 7.2667(9) Å and Z = 1. Eu2+ ions prefer one crystallographic Ba site in the structure and exhibit strong blue emissions at 440 nm. A new series of compounds RE4Zn4(SiO4)5 (RE=Y, La, Eu, Gd, Tb, Dy, Ho, Er), adopting an unprecedented new structure type, was discovered. Crystals of Y4Zn4(SiO4)5 were grown from a silica-rich eutectic melt and its structure was determined by single-crystal diffraction methods. It crystallizes in tetragonal space group P42/n with cell dimensions a = 9.3289(10) Å, c = 9.0509(18) Å and Z = 2. Selected photo-luminescence properties of lanthanide ions doped Y4Zn4(SiO4)5 are presented. High-purity MgS:Eu phosphors, exhibiting distinct cubic morphology, high luminescence efficacy, and stability against moisture, were synthesized. Thin films of early transition metal oxides (TiO2, HfO2, Nb2O5, and V2O5) have been deposited from peroxo-assisted aqueous solutions. The facile decomposition of peroxo ligands upon annealing allows smooth and efficient transformation of the precursors into high-quality films. Therefore, the films exhibit extraordinary performance in advanced optical and electrical devices, such as dielectric mirrors, microcavities, capacitors, and thin-film transistors (TFTs). The control over film thickness to a single-digit nm thickness is also demonstrated through the fabrication of TiO2-AlPO nanolaminates using simple beaker chemistry.
