Quick Facts
Biography
Chihaya Adachi, PhD, (born 26 October 1963) is a Japan-born scientist and lecturer specializing in organic electronics - materials science and device physics. Adachi is the Director of OPERA (Center for Organic Photonics and Electronics Research) in Kyushu University, a large multi-disciplinary team of physicists, chemists, and engineers from both academia and industry.
Adachi is widely recognized as an innovator in the development of materials for organic light-emitting diodes (OLED), pioneering a new technology known as thermally activated delayed fluorescence (TADF).
In 2015, Adachi co-founded Kyulux in Fukuoka, Japan, to commercialize hyper-fluorescence TADF emitters. Adachi serves as a scientific advisor and ex-officio board member of Kyulux.
Prof. Adachi serves on the Elsevier Orgnaic Electronics Editorial board.
Early career
Adachi held positions at Ricoh Co., Shinshu University, Princeton University, and at Chitose Institute of Science and Technology. He became a distinguished professor at Kyushu University in 2010, and his current posts also include director of Kyushu University’s Center for Organic Photonics and Electronics Research (OPERA) since 2010.
Education
Professor Adachi obtained the degree of Bachelor of Science from Chuo University in 1986. He went on to earn his Master of Science degree in Kyushu University in 1988. Adachi obtained his doctorate in Materials Science and Technology in 1991 from Kyushu University.
Research, patents and awards
Prof. Adachi published over 430 papers in the field of organic electronics. Adachi's lab in Kyushu University has filed over 180 patents since 1989. Prof. Adachi's work and achievements are regarded as fundamental to scientific understanding of OLED device mechanisms, structures and developments. Specific areas in which the Adachi's work was instrumental include highly efficiency phosphorescence emission, OLED host materials and OLED degradation.
In 2012 Prof. Adachi discovered a new class of light emitting materials that utilize thermally activated delayed fluorescence, or TADF. Since then his research activities are mainly focused on TADF and Hyperfluorescence OLED emission.
In 2014 the Society for Information Display(SID) awarded Prof. Adachi with its 2014 SID Fellow Award that honors individuals who have made a widely recognized and significant contribution to the field of information display.
In 2007 Prof. Adachi's paper "Relaxation of Roll-off Characteristics in Organic Electrophosphorescence diodes" won the Outstanding Poster Paper Award at the 7th International Meeting on Information Display (IMID2007). In July 2016 Prof. Adachi was one of the scientists recognized at the Japan Research Front Awards 2016. The Award, which is in its fourth year, was organized by the Intellectual Property & Science (IP & Science) business of Thomson Reuters. Other awards include the 2003 Funai Foundation for Information Technology FFIT Award, the 2004 dstinguished paper award on Organic electroluminescence (by the Japan Society of Applied Physics) and the 2004 Nano-Tech Award (IT&Electronics division).
In the 2007 Prof. Adachi received the Commendation for Science and Technology by the Japanese Minister of Education, Culture, Sports, Science and Technology. In 2016 Prof Adachi was awarded with the Japan Society of Applied Physics Fellow Award.
