Quantum Nanocrystal Research Lab

Hello! We are QNRL,
a research laboratory in the Department of Energy Science at Sungkyunkwan University.
QNRL stands for Quantum-confined Nano-crystal Research Laboratory, and we study quantum dots and semiconductor nano crystals,
as well as the devices that utilize them including electro-luminance or photo-voltaic such as light-emitting diodes (LEDs),
lasers, photodetectors, and solar cells, in various fields.

We design synthesis methods for nano crystals ranging from small clusters to those in the visible
and short-wavelength infrared (SWIR) regions, and use various techniques such as synthetic chemistry, spectroscopy, electron microscopy,
and computer modeling to analyze their properties and surfaces. In the process, we continuously explore new synthetic precursors
and methodologies, and develop strategies for controlling the nano crystal surfaces by analyzing their energy characteristics.
Moreover, we provide a systematic approach to exploring materials and developing additional synthesis and surface
modification strategies, using various characterization techniques such as optical spectroscopy,
electron microscopy, X-ray spectroscopy, NMR, X-ray diffraction, and electrical properties analysis.

We also utilize these synthesized nano crystals to produce solar cells and photodetectors, and conduct research to increase our
understanding of the materials and achieve the characteristics and efficiency required for next-generation devices. QNRL analyzes
the performance and properties of devices using various self-owned analysis equipment such as ellipsometry, current-voltage
characteristics, quantum efficiency measurements, transistors, TPV&TPC, and conducts optical and electrical property analysis
on single-dot to multilayer structures for device design. Recently, we have been conducting various projects
for quantum dot infrared sensors that have received attention both domestically and internationally.
More details on our research directions can be found in the RESEARCH section of our website.

Thank you for visiting QNRL, and we look forward to sharing our latest discoveries with you!
