This research project explores colloidal perovskite nanocrystals (NCs) and their assemblies into supracrystals for advanced photonic applications such as solar cells, LEDs, lasers, and quantum technologies. Perovskite nanocrystals exhibit size-tunable optical properties and quantum behaviors, making them ideal for next-generation devices. A key focus is on superfluorescence, a collective quantum phenomenon where excitons emit light coherently, potentially enabling ultra-efficient, low-threshold lasers.
Project Goals:
- Synthesize and assemble perovskite nanocrystals into supracrystals to study collective optical effects.
- Demonstrate superfluorescence and laser oscillation with reduced thresholds for high-performance photonic sources.
- Investigate lead-free perovskite alternatives (e.g., CsCuX₃) for sustainable device development.
The student will collaborate with interdisciplinary teams at Strathclyde, leveraging expertise in nanocrystal synthesis, assembly, and photonic characterization. Success could advance optical communications, nanoscale sensing, and quantum photonics for computing and precision metrology.
