We report a novel Unipolar light-emitting device architecture that operates using direct-current, field-driven electroluminescence of colloidally synthesized quantum dots (QDs). This device architecture. which is based only on transparent ceramics and QDs, enables emission from different color QDs and, for the first time. constant QD electroluminescence during Mended operation in air, unpackaged,
