Book Description
Metal chalcogenide nanomaterials are interesting due to their size dependent properties and potential use in numerous types of devices or applications. The synthetic methods of binary phase metal chalcogenide nanoparticles are well established, but finding simple ways to make even more complex nanostructures is important. To this end, two techniques were studied: the cation exchange of metal chalcogenide nanocrystals, CdE 2!MxEy (E = S, Se, Te; M = Pd, Pt) and the solution phase synthesis of ternary chalcogenide nanoparticles. The effects of cation solvation and the volume change ([Delta] V) of reaction on the equilibrium and the morphology change in the cation-exchange reactions of CdE 2!MxEy were investigated. A two-phase solvent environment was particularly efficient in increasing the thermodynamic driving force. The effect of [Delta] V of reaction on the morphology of the product nanocrystals was also investigated. Depending on the stress developed in the lattice during the reaction, product nanocrystals underwent varying degrees of morphological changes, such as void formation and fragmentation, in addition to the preservation of the original morphology of the reactant nanocrystals. The knowledge of the effect of ion solvation and [Delta] V of reaction on the equilibrium and product morphology provides a new strategy and useful guide to the application of cation-exchange reactions for the synthesis of a broader range of inorganic nanocrystals. Using a solution phase method, the morphology of CuInSe2 nanoparticles could be tuned from small 10 nm spheres to micron length nanowires by varying the relative amount of strong and weak surfactants passivating the surface. Oleylamine and trioctylphosphine oxide were chosen as the strong and weak surfactants, respectively. Small isotropic structures were formed when the oleylamine was the only surfactant with the size of the nanospheres increasing as the amount of oleylamine decreased. For the CuInSe2 nanowires, weakly-binding dioctylphosphine oxide (DOPO), an impurity in the TOPO, was found to be the key surfactant that enables the anisotropic one-dimensional growth. Detailed analysis of the structure of the nanowires indicated that they grow perpendicular to (112) planes, with twinning around the growth axis by ~60° rotation. The nanowires exhibit a saw-tooth surface morphology resembling a stack of truncated tetrahedral.

Book Description
In this book anisotropic one-dimensional and two-dimensional nanoscale building blocks and their assembly into fascinating and qualitatively new functional structures embracing both hard and soft components are explained. Contributions from leading experts regarding important aspects like synthesis, assembly, properties and applications of the above materials are compiled into a reference book. The anisotropy, i.e. the direction-dependent physical properties, of materials is fascinating and elegant and has sparked the quest for anisotropic materials with useful properties. With such a curiosity, material scientists have ventured into the realm of nanometer length scale and have explored the anisotropic nanoscale building blocks such as metallic and nonmetallic particles as well as organic molecular aggregates. It turns out that the anisotropic nanoscale building blocks, in addition to direction-dependent properties, exhibit dimension and morphology dependence of physical properties. Moreover, ordered arrays of anisotropic nanoscale building blocks furnish novel properties into the resulting system which would be entirely different from the properties of individual ones. Undoubtedly, these promising properties have qualified them as enabling building blocks of 21st century materials science, nanoscience and nanotechnology. Readers will find this book professionally valuable and intellectually stimulating in the rapidly emerging area of anisotropic nanomaterials. Quan Li, Ph.D., is Director of the Organic Synthesis and Advanced Materials Laboratory at the Liquid Crystal Institute of Kent State University, where he is also Adjunct Professor in the Chemical Physics Interdisciplinary Program.

Book Description
The chemical elements oxygen (0), sulfur (S), selenium (Se), tellurium (Te), and polonium (Po), belonging to group 16 of the periodic table, are called chalcogens. Chalcogenides are a class of chemical compounds consisting of at least one chalcogen anion and an electropositive element. When the electropositive element is a metal, it is called a 'metal chalcogenide.' Generally, the term chalcogenide is used to address sulfides, selenides, and tellurides rather than oxides and polonium compounds because of the strong non-metallic properties of oxygen and the strong metallic qualities of polonium. Due to the ability of the chalcogen to catenate and bind to numerous metal centers, various metal chalcogenides with different structures and compositions can be formed. The large and diverse family of metal chalcogenides can be classified in many ways; for instance, the chalcogen element present can be divided into sulfides, selenides, tellurides, and multi-chalcogen chalcogenides. Binary metal chalcogenides comprising a main group or transition metal and a chalcogen are widely explored for their distinctive chemical and physical properties and promising application in optoelectronics, photovoltaics, thermoelectrics, and photo-catalysis, and photodetection. Binary metal chalcogenides exist in many stoichiometries and structures.
