Abstract : SBIR phase I results include the development of a novel, aqueous based synthesis of metal chalcogenide quantum dot phosphor materials and the development of a video rate electrically addressed lasing pixel. The development of new phosphor systems will result in improved conversion efficiencies, an increased color palette, and enhanced spatial resolution of direct view and large screen displays. Our efforts have led to the development of ZnSe quantum dots through a novel aqueous based synthesis. In addition to the development of the nanocrystalline materials the phase I SBIR included the development of lasing pixel displays incorporating optical gain and scatterers. In this second area, we have demonstrated an electrically addressed lasing pixel for large screen display applications, which uses liquid crystal technology in a flat micro-cavity laser configuration.
