Ternary Quantum Dots

Ternary Quantum Dots: Synthesis, Properties, and Applications reviews the latest advances in ternary (I-III-VI) chalcopyrite quantum dots (QDs), along with their synthesis, properties and applications. Sections address the fundamental key concepts of ternary quantum dots, progress in synthesis strategies (i.e., organic and aqueous synthesis), and characterization methods (i.e., transmission electron microscopy, dynamic light scattering, etc.). Properties of ternary quantum dots are comprehensively reviewed, including optical, chemical and physical properties. The factors and mechanisms of the cytotoxicity of ternary quantum dot-based nanomaterials are also described. Since ternary chalcopyrite quantum dots are less toxic and more environmentally benign than conventional binary II-VI chalcogenide quantum dots, they are being investigated to replace conventional quantum dots in a range of applications. Thus, this book reviews QDs in various applications, such as solar cells, photocatalytic, sensors and bio-applications. Reviews fundamental concepts of ternary quantum dots and quantum dot-nanocomposites including the most relevant synthesis strategies, key properties, and characterization techniques Delves into the cytotoxicity of quantum dots looking at the factors and mechanisms that influence cytotoxicity including demonstration of cytotoxicity assays for in vitro and in vivo tests Touches on the many applications of ternary quantum dots including biomedical applications, applications in solar cells, sensing applications, and photocatalytic applications

This book outlines various synthetic approaches, tuneable physical properties, and device applications of core/shell quantum dots (QDs). Core/shell QDs have exhibited enhanced quantum yield (QY), suppressed photobleaching/blinking, and significantly improved photochemical/physical stability as compared to conventional bare QDs. The core-shell structure also promotes the easy tuning of QDs’ band structure, leading to their employment as attractive building blocks in various optoelectronic devices. The main objective of this book is to create a platform for knowledge sharing and dissemination of the latest advances in novel areas of core/shell QDs and relevant devices, and to provide a comprehensive introduction and directions for further research in this growing area of nanomaterials research.

A Quantum Dot Sensitized Solar Cell employing ternary or quaternary quantum dots represents an innovative approach to solar energy conversion. In this design, the utilization of three or four distinct types of quantum dots enables the solar cell to efficiently capture a broader spectrum of light. This enhanced light absorption is achieved through careful bandgap engineering, allowing the quantum dots to absorb different wavelengths of sunlight. The diverse composition of ternary/quaternary quantum dots contributes to improved charge separation and reduced recombination losses, fundamental factors in maximizing the efficiency of energy conversion. The advanced materials not only facilitate efficient electron injection into the semiconductor layer but also offer versatility in tailoring the optoelectronic properties of the solar cell. The multi-dot structure enhances light harvesting capabilities, increasing the likelihood of capturing photons across a wide range of the solar spectrum. This approach addresses limitations observed in traditional solar cells and holds promise for boosting overall performance in harnessing solar energy. The potential for multiple exciton generation within ternary/quaternary quantum dot systems adds an intriguing dimension to their functionality, offering the possibility of generating multiple electron-hole pairs from a single absorbed photon. This phenomenon has the potential to significantly enhance the quantum efficiency of the solar cell.
