Ternary Quantum Dots : Synthesis, Properties, and Applications

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

Professor Oluwafemi is a fully-fledged academic that is involved in Teaching & Learning, Research, Community Engagement, staff and student mentorship among many other activities. His research interest is in the synthesis of binary, ternary and quaternary semiconductor nanomaterial and nanostructures such as quantum dots, metal nanomaterials, core-shells, doped nanostructures and polymer nanocomposites for different applications which includes biological, (basically for cancer treatment ie imaging, labelling, drug delivery photodynamic therapy and photothermal therapy), optical (development of optical devices), environmental (sensing and determination of environmental pollutants), nanotoxicology and water treatment. He is also involved in the indigenous knowledge system (IKS) for value added chain using different South African medicinal plants. This involves isolation, extraction, biological activity testing, and synthesis of nanomaterial using the plant extract and packaging for pharmaceutical purposes.
