Message from the Chair

  • Greetings!
  • While the demonstration of the first OLED emitting thermally activated delayed fluorescence (TADF) in Advanced Materials in 2009 by OPERA at Kyushu University gave a glimpse of TADF's potential, OPERA's report in Nature in 2012 of a TADF-based OLED with an internal quantum efficiency of nearly 100% grabbed the attention of researchers world-wide and established TADF as a truly promising technology.
  • In the five years since then, extensive studies around the globe have been conducted, leading to rapid developments in TADF materials, devices, and physics and further strengthening TADF's position as the third-generation of OLED emitters.
  • As a follow-up to the 1st International TADF Workshop in Fukuoka, we are delighted to announce the organization of the 2nd International TADF Workshop to share the recent advances and future direction of TADF science and technologies.

  • Welcome to Fukuoka!

  • Chihaya Adachi
    Chair of the 2nd International TADF Workshop
    Director of the Center for Organic Photonics and Electronics Research at Kyushu University

  • Dear OLED Community,
  • I am very proud that Kyulux will serve as a sponsor for the 2nd International TADF Workshop at Kyushu University in Fukuoka, Japan. It is the birthplace of TADF technology and my alma mater. Many prominent international researchers in the TADF and OLED fields will be giving exciting talks. The presentations will cover a wide gamut of cutting-edge research in TADF chemistry, devices, and applications.
  • July will be an ideal time to enjoy the stunning mountain and ocean scenery of Fukuoka. You can learn why Fukuoka is consistently voted one of the top cities in the world by travel publications. Fukuoka's beaches, culinary scene (particularly its famous seafood), arts, and shopping are huge attractions for international tourists.
  • I would like to extend a warm welcome to this tremendous conference and look forward to speaking with you at the event.

  • With warmest regards,

  • Christopher Savoie, Ph.D., J.D.
    CEO of Kyulux and Kyushu University Alumnus, Ph.D. '99

  • Located in the southern Japanese city of Fukuoka, which is known in Japan for its delicious cuisine and fresh fish, Kyushu University opened its new Ito Campus on the Itoshima Peninsula in 2005. A short ride from a beautiful coastline and magnificent mountains, Kyushu University has much to offer in terms of both leading research and an enjoyable daily life.

  • The campus is easily accessible from Fukuoka Airport via public transportation. After a 35-minute ride on the subway, transfer at Kyudai-Gakkentoshi Station for a 15-minute bus ride to the campus. The Workshop is then a short walk from the Kyudai Big Orange Mae bus stop. Detailed directions will be provided soon.
