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.
Steckel et al. (2003) studied this question.
