Colloidal quantum dots (QDs) have been a subject of extensive research for several decades for their unique optical properties and versatile applications. Ongoing refinements in their synthesis have enabled the production of high-quality QDs with precise control over their size, shape, and compositions. Specifically, core-shell and other types of heterostructure QDs have garnered significant attentions, resulting in advancements that enhance their optical properties, morphology control, material stability, and their diverse applications in real-life. In this talk, I will discuss about our works on the synthesis of cadmium-chalcogenide and perovskite-type QDs and QD-metal heterostructure nanomaterials. This includes a discussion on how these anisotropic QDs can be used as fundamental building blocks for constructing intricate superlattice materials. I will also talk about the potential applications of the colloidal QD-metal hybrid nanocrystals in photocatalytic reactions, presenting our experimental findings alongside theoretical insights.
