Book Description
Colloidal semiconductor quantum dots are novel materials whose electronic and optical properties can be greatly enhanced from the bulk semiconductor properties by quantum confinement. A brief introduction to colloidal quantum dots and the effect of size on its electronic and optical properties will be given. CdSe/ZnS, PbS, and PbSe quantum dots will be described in more detail with regards to the research done in this dissertation. CdSe/ZnS quantum dots have luminescence that can be tuned in the visible, making them particularly suited for fluorescent labels in biological applications. In particular, their potential use as voltage sensors to detect cell membrane potentials and sphingosine phosphorylation will be discussed. PbS and PbSe quantum dots emit in the near infrared, wavelengths that are important to telecommunications. Their small third-order nonlinearity and relatively long (microsecond) lifetimes will be discussed in terms of dielectric screening. Fluoresence resonant energy transfer between PbS quantum dots will also be discussed.

Book Description
This book introduces readers to a wide range of applications for elements in Group 16 of the periodic table, such as, optical fibers for communication and sensing, X-ray imaging, electrochemical sensors, data storage devices, biomedical applications, photovoltaics and IR detectors, the rationale for these uses, the future scope of their applications, and expected improvements to existing technologies. Following an introductory section, the book is broadly divided into three parts—dealing with Sulfur, Selenium, and Tellurium. The sections cover the basic structure of the elements and their compounds in bulk and nanostructured forms; properties that make these useful for various applications, followed by applications and commercial products. As the global technology revolution necessitates the search for new materials and more efficient devices in the electronics and semiconductor industry, Applications of Chalcogenides: S, Se, and Te is an ideal book for a wide range of readers in industry, government and academic research facilities looking beyond silicon for materials used in the electronic and optoelectronic industry as well as biomedical applications.

Book Description
Nanotechnology is an interdisciplinary field comprising materials scientists, chemists, physicists, and engineers dedicated to understanding the chemistry behind the associated synthesis, purification, modification, and applications. Already, nanotechnology has been instrumental to advances in medicine, electronics, catalysis, and cosmetics. The work of nanotechnologists has enabled society to move from the current “Silicon Age” into a new “Nano Age.” These alternatives to Si-based technologies are expected to combine the optoelectronic properties of bulk inorganic semiconductors with the benefits of additive device manufacturing—low cost, large area, and solution-based processes. This primer focuses on a class of nanomaterials known as colloidal quantum dots. Known for their solution processability and size-dependent optoelectronic properties, the study of colloidal quantum dots has garnered significant attention from the research community. The goal of this primer is to equip newcomers with the introductory knowledge and tools necessary to enter the field. As such, the scope of our work focuses on the synthesis and characterization of quantum dots; where possible, we point the reader to further reading specific to applications.
