NSRRC User Pi-Tai Chou's Research Set the World Record of "High-Performance OLED Emission"
With the support of the “Academic Summit Program” from the National Science and Technology Council (NSTC), the research team led by NSRRC user, Prof. Pi-Tai Chou in Chemistry at the National Taiwan University, successfully broke the world record of “high-performance organic light-emitting diodes (OLED) emission” held by the team itself, from the 804 to 1,000 nanometers. NSRRC scientist Dr. Wei-Tsung Chuang, also a member of the research team, attended the press conference held at NSTC on December 7.

This research achievement was published in Nature Photonics, a top-ranking journal in the field of photonics. Using TLS 01C2 endstation at the Taiwan Light Source, the team successfully proposed that chemical deuterated OLED molecules with ordered crystalline packing can efficiently reduce high-frequency vibrations leading to intense emission in the second near-infrared NIR(II) region. This significant finding is expected to be applied to real-time biomedical imaging and biochemical sensing analysis in the future, making feasible the wearable sensor devices for biomedical applications.
