Abstract :
This paper describes the design, fabrication, and characterization of a microcavity-electroluminescence (EL) device based on colloidal semiconductor nanocrystal quantum dots (NQDs). We observed a significant reduction in EL emission bandwidth from the fabricated device. Enhancement in emission efficiency and output directionality will be reported as well.
