Chihaya Adachi
- Distinguished Professor
- Kyushu University, Japan
His research focuses on (I) the rational design of luminophores for energy-efficient visual displays and flat panel lighting based on organic light emitting diode (OLED) and device architectures; (II) clarification of excitonic processes in organic thin films, and (III) pioneering next-generation quantum molecular devices.
His research combines the areas of chemistry, physics, and electronics to advance the field of organic light-emitting materials and devices from both the materials and device perspectives through the design of new molecules with novel properties, the study of processes occurring in individual materials and complete devices, and the exploration of new device structures.
