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.

All these materials were successfully applied for the fabrication of various electronic devices such as electrical circuits, transparent electrodes, flexible thin film transistors, RFID antennas, photovoltaic devices, and flexible touch panels. In this paper, we focus on the basic properties of these nanomaterials, in view of their application in conductive inks, on obtaining conductive patterns by 2D and 3D printing, and on various methods of post-printing treatment.
