With the support of the Macromolecular, Supramolecular and Nanochemistry (MSN) Program in the Division of Chemistry, Professor Liangfeng Sun and his group at the Bowling Green State University are developing tiny sheet-like materials (called nanosheets) that can emit highly controlled light. These materials are designed so that the thickness controls the “color” of light they emit, while their large area allows for multiple light particles (photons) to work together in a coordinated way - key for future quantum technologies. Their work focuses on creating and studying these nanosheets to produce coherent photons in the near-infrared range, which is useful for secure quantum communication through existing fiber-optic networks. The project also supports education at multiple levels: undergraduate and graduate students gain hands-on experience in cutting-edge science, high school students participate through summer research, and outreach efforts extend to the Dayton, Ohio area to engage with local universities and high-tech labs, including the Air Force Research Lab. This collaboration aims to help build a strong future workforce in quantum science and technology. The research team will: (1) investigate amplified spontaneous emission, giant oscillator strength transitions, and superfluorescence in colloidal PbS nanosheets; (2) examine the effects of surface states, Auger recombination, and exciton funneling on optical properties; and (3) explore how trions, polarons, and exci
