Metal-assisted Delayed Fluorescent Emitters for Organic Displays

Project: Research project

Description

Brief description of the potential commercial impact: 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. 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. However, the existing phosphorescent emitters require the utilization of heavy metal ions like Iridium and Platinum, which could be potentially expensive due to their low natural abundance on the earth. On the other hand, metalassisted 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. Brief description of the current commercialization plan Arizona Technology Enterprises (AzTE) is the exclusive intellectual property management and technology transfer organization for Arizona State University. AzTE will work with faculty, investors and the industry partners to speed the flow of innovation from research laboratory at ASU to the marketplace. The proposed project is built on a strong relationship between Dr. Li and Dr. Polasko through frequent information exchange between the PI and I-Corps Mentor, which have led to the successful licensing process of Dr. Lis over 8 patent applications to the private industry in the past 5 years. In a short period of 6-month, the team will fully characterize some examples of metal-assisted delayed fluorescent emitters in device settings, like the device efficiency, color quality and operational lifetime. By comparing the emissive materials from ASU technology and the state-of-the-art emitters in research field, we will summarize the pros and cons of metal-assisted delayed fluorescent emitters. At the end of this program, the team will decide if ASU technology is ready for immediate commercialization or a long-term development plan will be needed for such an emerging technology.
