  We focus on the material engineering based on light atoms for the purpose of realizing a wide-range electronic/band property tuning, from insulators (e. g. h-BN), semiconductors (carbon nitride) to conductors (carbon). This should be of fundamental importance in understanding many other interesting properties for a material, including optical, electrical, transport, optoelectrical properties, etc. We explore these materials for luminescence, bioimaging/medical, energy storage and photoelectrical conversion applications.

  Light atoms including boron, carbon, nitrogen and oxygen can form various building blocks that could be used for further construction of many materials. These atoms locate at the neighboring positions at the second row of the periodic table, which are close with each other and can effectively form conjugated structures. It is expected that the structures and properties of this type of materials are highly tunable through rational designs.

(2020.10.16) Carbon and oxygen co-doping of BN realizes boosting affinities for hydrogen storage. The co-doped BN with the specific surface area of only 397 m2 g-1 shows higher H2 storage capacity compared with those of the undoped BNs having the SSA up to 1290 m2 g-1. See details in "Hydrogen Storage in Carbon and Oxygen Co-Doped Porous Boron Nitrides".
