Ten-fold improvement in the photoluminescence quantum efficiency of quantum-size-effect-tunable (1000-2000 nm) and solution-processed PbS nanocrystal films

PbS nanocrystals for infrared applications have previously shown to have very low photoluminescence quantum efficiency (/spl sim/ 1%) when solution-processed into the solid state. We show a ten-fold improvement through the use of polymer-nanocrystal composites.
