Welcome to the Nanoscale Optoelectronics Group
Our research is dedicated to pioneering the next generation of earth-abundant perovskite nanomaterials and their programmable self-assembly for emerging applications in photonics, magnetism, and optoelectronics. We explore advanced synthesis strategies—including wet chemical methods, hot-injection protocols, chemical vapor deposition (CVD), and antisolvent-assisted crystallization—to engineer nanostructures with tailored properties for future technologies such as quantum photonic circuits, spintronic devices, and flexible energy systems.

Perovskites: the new generation of optoelectronics

Lead halide perovskite (LHP) nanocrystals (NCs) with the formula ABX₃ (A = monovalent cation, B = divalent metal cation, X = halide) have emerged as promising semiconductors for optoelectronic applications due to their tunable bandgaps, high absorption coefficients, long carrier diffusion lengths, and excellent defect tolerance. Their bright photoluminescence and solution-processability make them ideal for low-cost fabrication.

Owing to these properties, LHP NCs are being extensively studied for high-efficiency solar cells, LEDs, and lasers. They also show potential in sensors, photodetectors, and future applications such as electric vehicle batteries and neuromorphic devices.
