Funding Type: SBIR

PROJECT OBJECTIVE

This project proposes to use commercially available thermally activated delayed fluorescence (TADF) materials to develop highly efficient and stable blue devices and incorporate them into tandem white OLEDs, which will help minimize the deleterious effects of existing blue stack geometries. Phase I goals include quantification of key photo-physical performance characteristics of TADF emitters and identification of suitable materials, leading to the commercial development of practical OLEDs with higher blue efficiencies resulting in improved overall efficacy. Subsequent phases will include accelerated lifetime testing and systematic analysis of degradation routes of the successful Phase I materials, which will enable reduction of chemical instabilities by synthetic modification. This research pathway is expected to lead to further development and commercialization of OLED lighting products.

PROJECT IMPACT

This research pathway is expected to lead to further development and commercialization of OLED lighting products that would greatly benefit the lighting market. Incorporation of efficient and stable blue component(s) into white OLEDs will help to minimize the deleterious effects of existing blue stack geometries.
