Zhilong ZHANG

Biography

  • Professor Zhilong Zhang received his International Baccalaureate diploma from St Peter’s College Adelaide (2008), his undergraduate degree from the Australian National University (2012) and his PhD from the University of New South Wales (2018). He then joined the Cavendish Laboratory at the University of Cambridge as a postdoctoral researcher (2018-2022) and obtained an EU Marie Skłodowska-Curie Fellowship in 2019. He joined the SCUT in 2022 and currently leading an independent research group. His current research interests include energy transfer mechanism in nanomaterials, ultrafast spectroscopy, optoelectronic devices (LEDs, solar cells and photodetectors), photon up/down conversion and new concepts of energy conversion. He is the author or co-author of more than 50 peer-reviewed scientific publications. He is a native Chinese and English speaker, and fluent in Japanese.

Research Interests

  • Professor Zhang’s research focuses on the photo-physics and optoelectronic properties of a range of nanomaterials, including quantum dots, organic molecules, 2D materials, and their hybrids. He is particularly interested in studying the fundamental physics of nanomaterials, as this is key to the performance of applications based on these materials. His group is also actively working on applications such as photon up/down conversion, light-emitting diodes, and energy conversion.

  • Examples of ongoing projects include:

  • 1.Energy transfer mechanisms among quantum dots, organic molecules, lanthanides, etc.

  • 2.Using ultrafast transient spectroscopy and microscopy to reveal exciton dynamics.

  • 3.Photon up/down conversion materials.

  • 4.NIR LEDs.

  • 5.New concepts for energy conversion.

  • All students in his group receive rigorous training in the synthesis of various types of quantum dots, characterization techniques for photo-physical properties (particularly by using ultrafast transient absorption and photoluminescence spectroscopy), and the fabrication and characterization of optoelectronic devices.
