A PbS quantum-cube: conducting polymer composite for photovoltaic applications

Abstract:

We have developed a new non-polar synthesis for lead sulfide (PbS) "quantum-cubes" in the conjugated polymer poly-2-methoxy, 5-(2-ethyl-hexyloxy- p -phenylenevinylene) MEH-PPV. The conducting polymer acts to template and control the quantum-cube growth. Transmission electron microscopy of the composites has shown a bimodal distribution of cube sizes between 5 and 15 nm is produced with broad optical absorption from 300 to 650 nm. Photoluminescence suggests electronic coupling between the cube...
