With the support of the Macromolecular, Supramolecular and Nanochemistry (MSN) Program in the Division of Chemistry, Professor Mikhail Zamkov of Bowling Green State University will explore a new chemical method for improving the optical performance of small semiconductor nanoparticles, known as colloidal nanocrystals. These materials could serve as the foundation for future quantum technologies, including secure communication networks, quantum-enhanced sensors, and advanced computing systems. Presently, the practical use of colloidal nanocrystals in such applications is hampered by inherent defects in their crystal structure that lead to unpredictable optical flickering and color changes, making nanocrystals unreliable for demanding quantum applications. This project will address this issue by developing a halide-based chemical treatment to “repair” imperfections in the nanocrystal lattices. By restoring the structural order, this method is expected to reduce the noise in the emitted light and enable a stable production of single or paired photons, which represent an essential requirement for any quantum information system. The research will also focus on theoretical modeling to understand how halide ions interact with atomic-scale defects. In addition to its scientific goals, the project will contribute to workforce development by ensuring the undergraduate student participation in hands-on research and hosting outreach activities in chemical sciences.
