Quantum Dot Displays

Speaker: Dr. Xiao Wei SUN
Affiliation: Southern University of Science and Technology (SUSTech)

Hosted by The Optical Society (OSA) and SPIE Student Chapter


Quantum dots (colloidal) are semiconducting nanocrystals, also known as artificial atoms. Due to quantum confinement effect, the emitted color of the QD is directly dependent on its size. With years of study, the start-of-the-art synthesized QDs are known for their high quantum yield and narrow emission bandwidth, making it suitable for practical applications for displays, though there is still some distance for lighting. In this talk, we present highly efficient colloidal core-shell quantum dots, quantum rods and perovskite nanocrystals for emerging energy-saving quality display applications. We applied these luminescent materials to make various devices including quantum dot luminescent microspheres (QLuMis) for on-chip InGaN LED packaging (photoluminescent applications), and assembling aligned quantum rod to make polarized emission films. These nanocrystal materials were also used to make high efficiency quantum dot light-emitting diodes with high efficiency.


Dr. Sun obtained his PhD in electronic engineering from the Hong Kong University of Science and Technology. He is presently a Chair Professor and Head of the Department of Electrical and Electronic Engineering in the Southern University of Science and Technology, Shenzhen, China. Before joining Southern University of Science and Technology, he had been working at Nanyang Technological University, Singapore as a Full Professor. He was the Director of Microelectronics Center at Nanyang Technological University. He was awarded the Nanyang Award for Research and Innovation in 2009, the 1000 Talent Award by the Chinese Government in 2012, and the Jacques Beaulieu Excellence Research Chair of INRS (Institut national de la recherche scientifique), Quebec, Canada in 2013. He is an Academician of the Asia-Pacific Academy of Materials. He is the fellow of several academic societies including Optical Society of America (OSA), SPIE, Society for Information Display (SID), and Institute of Physics (IoP, UK). He is the founder and president of the Society for Energy Photonics, a non-profitable organization promoting photonics technologies to solve energy crisis and combat global warming and climate change. He is the Chair of OSA Shenzhen Section and an OSA traveling lecturer. He is presently an Adjunct Professor in the Department of Electrical and Electronic Engineering, Hong Kong University of Science and Technology. His main research presently is on semiconductor nanocrystals for power-saving high-quality displays and lighting.
