Abstract
The 2023 Nobel Prize awarded to Moungi G. Bawendi, Louis E. Brus, and Alexei Ekimov “for the discovery and synthesis of quantum dots” (QDs) marks a milestone in the field to which I devoted the past 30-years of my career. In this perspective, I reflect on key concepts and directions in my research journey. I began by exploring the “artificial atom” nature of QDs while advancing the development of III-V QDs. Shape control, particularly in rods, captured my attention due to its impact on dimensionality related properties. I also discovered semiconductor-metal hybrid nanocrystals and uncovered synergetic effects, highlighting their transformative role in photocatalysis and heavy doping. My work extended to QD applications in displays and, more recently, to forming coupled QD molecules, continuing the artificial atom theme. I conclude by outlining future directions and challenges, envisioning a bright future for this vibrant field at the intersection of materials and physical chemistry.
