Our research is currently focusing on

(1) Plasmonics of noble metal nanocrystals,

(2) Multifunctional nanostructured materials.

¡@

The first involves

(i) Design and synthesis of metal nanocrystals with specific plasmonic properties,

(ii) Assembly into plasmonic crystals at different length scale,

(iii) Plasmon coupling,

(iv) Refractive index sensitivities and related sensing devices,

(v) Plasmon-enhanced spectroscopy (Raman, fluorescence, absorption, nonlinear),

(vi) Coupling between plasmonic and molecular resonances.

¡@

The second involves

(i) Optical nanostructured materials,

(ii) Photocatalytic materials,

(iii) Photovoltaic materials.

¡@

These projects are highly inter-related and interdisciplinary. We aim at both fundamental understanding and potential applications. Students who are interested in these directions and have backgrounds in physics, chemistry, and/or materials science are welcome to join my group to pursue these exciting studies.
