Large area (mm 2 in size) infrared electroluminescent devices are demonstrated using colloidally grown PbSe quantum dots (QDs) in organic host materials. By changing the QD size the electroluminescence is tuned from λ = 1.33–1.56 μm. The fabrication of this light‐emitting device (see Figure) combines the thin film processing techniques available to organic materials with the tunable optical properties of PbSe QDs.
