We are a group of young scientists and engineers enthused to design and synthesize novel photocatalysts and study interactions in nanokrystals for self-assembled architecture. Through solid understanding on light-matter interaction and colloidal forces, we design nanostructures that convert photons into useful forms of energy such as chemical potential.

Research Highlights

S. Lee et al., “Thin Amorphous TiO2 Shell on CdSe Nanocrystal Quantum Dots Enhances Photocatalysis of Hydrogen Evolution from Water,” JPCC (2014). [link]


Amorphous titania, typically considered a poor photocatalyst, turns out to enhance photocatalysis of water splitting when it forms a thin layer on another photocatalyst particle.

Research Highlights

J.Y. Woo et al., “Ultrastable PbSe Nanocrystal Quantum Dots via in Situ Formation of Atomically Thin Halide Adlayers on PbSe(100),”
JACS (2014). [link]


Our simple in situ wet-chemical passivation scheme will enable broader utilization of PbSe NQDs in ambient conditions in many optoelectronic applications.

Research Highlights

J. Lim, B. Jeong et al., “Influence of Shell Thickness on the Performance of Light-Emitting Devices Based on Core/Shell Heterostructured Quantum Dots,”
Adv. Mater. (2014). [link]


Size matters: thicker shell in core/shell heterostructure quantum dots helps improve external quantum efficiency of light-emitting devices. Energy transfer and charging turn out to be main culprits for reduced efficiency and luminance.

Research Highlights

D. Kim et al., “Self-organization of nanorods into ultra-long range two-dimensional monolayer end-to-end network,”
Nano Lett. (2015). [link]


We present a 2-D, milimeter-scale network of colloidal CdSe nanorods in monolayer thickness through end-to-end linking. Our findings provide important design criteria for 2-D assembly of anisotropic nanobuilding blocks.
