Our group researches the surface chemistry of colloidal nanocrystals, encompassing surface treatment and ligand exchange techniques to enhance stability, efficiency, and functionalization.
Quantum Dots
What is Quantum Dots?
Quantum dots (QDs) are semiconductor particles a few nanometres in size with tunable optical and electronic properties by controlling their sizes via quantum confinement effects.
Our group focuses on a wide range of nanomaterials synthesis including QDs, perovskites and nanorods, as well as controlling the surface properties of nanomaterials.

QLED (Quantum dots-Light Emitting Diode)
Quantum dots can emit precisely colored light because the particle size is controlled by the quantum confinement effect, resulting in accurate and efficient light emission.
Our group specializes in fabricating QLEDs by employing QDs for emissive layer, while also enhancing their electrical properties.
QLED Design and Fabrication
Our group is developing and designing RGB light-emitting QLED fabrication with high color purity and efficiency.
We also focus on optimizing charge transport layers and interlayer interfaces, including the hole transport layer and electron transport layer, to enhance device stability and efficiency.
