Abstract:

Large area (mm2 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.
