Organic Light Emitting Diodes (OLEDs) have been considered as alternate for the next generation of displays and illumination devices, which has received great attentions from academia and industries. The proposed project converges at the interface of synthetic organic chemistry, materials science and engineering, semiconductor physics and device engineering to further develop OLEDs. In order to achieve the maximum device efficiency (i.e. converting all of injected electron to photons), it will require emissive materials to harvest all of electron-generated exactions. The knowledge research gain from this project will help to understand the fundamental mechanisms governing the radiative decay process of organic excitons including the emission efficiency and the shape of the emission spectrum.

The new classes of metal-assisted delay fluorescence materials in this project will significantly contribute to continuing efforts towards developing a cost-effective displays and solid state lighting. The existing phosphorescent emitters require the utilization of heavy metal ions like Iridium, which could be potentially expensive due to their low natural abundance on the earth. On the other hand, metal-assisted delay fluorescence materials could potentially utilize all of electro-generated excitons and rely on more naturally abundant metal elements. Such technology will provide more cost-effective alternative emissive materials for organic displays and solid state lighting.

Project Report

Organic Light Emitting Diode (OLED) has been considered as alternate for the next generation of displays and illumination devices, which has received great attentions from academia and industries. Recently, OLEDs have been manufactured in large scales as displays for mobile and hand-held devices like smartphones and tablet. In an anticipated near future, OLED will be used to fabricate for large flat panel TVs and illumination devices. Our I-Corps team is a three member team, which includes Prof. Jian Li as a PI, Mr. Nathan Bakken (i.e. a Ph.D. student) as an Entrepreneurial Lead, and Dr. Kenneth J. Polasko (i.e. the executive director at Arizona Technology Enterprise) as an I-Corps Mentor. The team is built upon the PI’s research expertise, an Entrepreneurial Lead’s unique background in pursuing doctor’s degree in science with pre-awarded MBA degree and the Mentor’s extraordinary career experience in technology generation, transfer, and commercialization. In the span of the past 18 month, our team were trained in I-corps program and gained preliminary knowledge for technology commercialization and business development. Then our team has applied the knowledge we learned from this program to explore the commercialization potential of the metal-assisted delay fluorescence technology created at ASU for organic displays and lighting applications.
