Advancements in the development of energy efficient light sources using environmentally friendly technology and material-efficient processing methods have the potential to generate multiple economic benefits. Such expected benefits include reduced power consumption, reduced greenhouse effects and reduced production of hazardous wastes. QD Vision proposes the development of a flexible quantum dot light emitting device (QD-LED) technology that utilizes all-printed colloidal inorganic materials for the emissive, charge transport and metallic layers. Solution processing enables lower cost while the use of inorganic materials affords higher performance and stability. Key technology development areas for this program include the development of materials and synthesis methods for preparing cadmium-free semiconductor nanocrystals that can emit light across the visible range of the spectrum, the development of solution-processable material systems and deposition techniques, and the development of an efficient LED architecture based entirely on solution-processed inorganic nanoparticles.
