Since the first synthesis of nearly monodisperse quantum dots (QDs) in 1993, commercially relevant QDs have been produced on kilogram scales for luminescent devices, ranging from displays to lighting. Recently, there has been a significant surge in interest specifically in III-V QDs and their core-shell structures. This interest is largely due to their unique properties and growing applications in the field, especially in the near- infrared region, which promises to open a plethora of new applications. This surge has been fueled by new synthesis protocols that have made III-V QDs more readily accessible. The precise size control achievable with these materials have provided a new platform for exploring semiconductor interfaces and understanding the optical properties of defects. Advanced synthesis precursors, more covalent materials, surface functionalization, and doping have emerged as the frontier areas in III-V QD research. In these endeavors, many exciting discoveries are being made. This symposium will bring together leading scientists in these forefront areas, focusing particularly on the advancements and applications of III-V QDs and their core-shell structures.
