We present a novel technique for room temperature, solution-based fabrication of alternating current thin-film electroluminescent (AC-TFEL)
devices using phosphor-doped nanocrystals. Synthesis for stable
ZnSe/ZnS:Mn/ZnS nanocrystals that exhibit a quantum yield of 65 +/- 5% is
outlined, and their electroluminescence is demonstrated in structures
consisting of only wide band gap ceramic layers. Both the nanocrystal and
the ceramic films have minimal absorption across the visible light
spectrum, enabling us to demonstrate transparent AC-TFEL devices.
