HOME>>About Us


Our research group, established in 2013, is affiliated with the Nano Characterization Laboratory of the National Center for Nanoscience and Technology. It is a young and energetic research and innovation team, which is composed of 4 researchers, 2 associate researcher, 2 senior engineers, 4 engineers and many Ph.D. students, master students, joint training students.

The main research fields are:

1.Study on the properties of graphene plasmons and related micro-nano optical properties of two-dimensional nanomaterials and heterostructures;

2. Field emission X-ray source;

3.Research and development of detection system based on QCM dynamic blood glucose / humoral ion.

Under the leadership of researcher Qing Dai, our research group has undertaken a number of domestic and international cooperation such as the major equipment project of National Natural Science Foundation, general projects, 973 project of the Ministry of Science and Technology, and foreign cooperation projects of the Chinese Academy of Sciences.

Group leader: 

Qing Dai is distinguished researcher of the Chinese Academy of Sciences, won the 15th "China Youth Science and Technology Award" and the National Science Fund for Distinguished Young Scholars, the Fellow of The Optical Society of America and The Royal Society of Chemistry, TWAS YOUNG AFFILIATE of The World Academy of Science.


In 2003-2007, he completed the undergraduate and masters course (MEng) at Imperial College of Technology, and in 2011 obtained the doctorate degree from Cambridge University, and then engaged in postdoctoral research at the Optoelectronics Research Center of Cambridge University. In 2012, he was elected to the Junior Research Fellow of Wolfson College of Cambridge University and in May joined the National Center for Nanoscience and Technology.


Mainly engaged in the photonic performance regulation and device research of nanomaterials, including the construction of new nanophotonic devices based on graphene plasmons, and the design of high-performance electron sources based on the mechanism of light field driving ultrafast electron emission.

He published more than 130 SCI papers in international academic journals, including 1 article in Nature (corresponding author), 1 article in Nature materials (corresponding author), 5 articles in Nature Commun. (corresponding author), 1 article in Phys. Rev. Lett. (corresponding author) and 9 articles in Adv. Mater. Related results were highlighted by scientific media such as Nature, Nature Photon. Applied for 52 national invention patents and 26 were authorized (including 1 PCT patent). As the executive chairman, he held many high-level academic conferences such as the Xiangshan Science Conference and ChinaNANO Photonics Branch. Currently serves as the associate editor for Nanoscale and Nano Today, and has been the contributing reviewer for journals such as Nature and Nature Mater. He has won many academic honors such as the 15th China Youth Science and Technology Award, 2019 most influential paper award, 2020 China Optics top ten progress award, and the Lu Jiaxi Young Talent Award of the Chinese Academy of Sciences.

Graphene plasmon and 2D nanomaterial’s optical properties

Graphene plasmons have high compression ratios, great local optical field enhancement, and are electrically tunable (tunable from terahertz to mid-infrared). However, due to the single-atom-layer two-dimensional structure of graphene (each atom is in a s
