Colloidal quantum dots bring a new level of freedom to light–matter engineering. Their tunable optical properties and solution-based fabrication open directions that conventional semiconductors cannot easily reach. By building on these strengths, we aim to turn quantum dots into practical platforms for next-generation photonic and light-emitting technologies. Our work focuses on the design and synthesis of semiconductor nanocrystals, integrating computational modeling with chemical approaches. This combined strategy allows the creation of well-defined quantum dot structures as a foundation for photonic studies. Exploring how quantum dots — down to the single-dot level — interact with light through advanced steady-state and ultrafast spectroscopic techniques. Chemical methods enable the synthesis of nanocrystals with targeted structures and compositions. Their accuracy is verified through structural characterization techniques such as TEM, XRD, XPS, and ICP-AES, ensuring reliable feedback for synthesis.
