Research Interests

Our research focuses on the assembly, property and application of functional nanostructured optical/photonic materials. Through various self-assembly strategies, we aim to fabricate novel functional nanostructures and nanodevices with tunable properties for various demanding applications, especially solar energy conversion fields. Specifically, our research topics include:

• Smart Nanoscale Optical Materials

• Assembly of Nonspherical Colloidal Particles into Functional Structures

• Solar Light Driven Carbon Dioxide Reduction
