Semiconductor nanocrystals (NCs), thanks to tunability and control afforded by quantum confinement effects with unique properties, have been broadly applied in light emitting diodes displays, chiral sensing and asymmetric catalysis, etc. However, a systematic control of these NCs was extremely difficult not to say impossible. Thus, it is still mandatory and relevant to find out an effective synthetic approach to achieve semiconductor NCs with tunable properties. In this work, we studied the precise control of quantum rods synthesis, and used them for chirality and laser-induced deposition purposes.
The anisotropic factor of circularly polarized luminescence (CPL, glum) can reach 8.5×10-4, and the the raito of single-tipped HNPs could be improved significantly from 42% to 81% in Au-CdSe/CdS HNPs .

poster

The Institute of Physics and IOP Publishing, in partnership with the Chinese Physical Society (CPS) and the University of Science and Technology of China (USTC) are proud to have brought together the international quantum science community online for this inaugural conference.


Early career and leading researchers from universities, industry and government worldwide came together to share, learn and collaborate on the latest research and emerging areas of high interest across quantum science and technology. The broad themes covered by Quantum 2020 included:

Quantum communication;
Quantum computing and quantum simulation;
Quantum sensing, metrology and imaging;
Quantum information theory, software and algorithms;
Quantum foundations;
Quantum technology in industry.
The four-day event featured talks from world-renowned scientists, interactive poster sessions and two exciting panel discussions on the themes of Quantum Technology in Industry and Quantum Technology Programmes Around the World.
