Colloidal semiconductor nanocrystals : We present a hybrid inorganic–organic near‐infrared light‐emitting device (see picture), which comprises a blend of a blue–green emitting, hole‐conducting conjugated polymer, methyl‐substituted ladder‐type poly( para ‐phenylene), and HgTe nanocrystals. The demonstrated device emits at the telecommunications wavelength of 1.3 μm, while the exceptionally broad spectral range covered by HgTe nanocrystals allows further spectral tunability in the near‐infrared region.
