Multi-heterojunction nanoparticles, methods of manufacture thereof and articles comprising the same

摘要

Disclosed herein is a semiconducting nanoparticle (100) comprising a one-dimensional semiconducting nanoparticle (102), for example a nanowire, having a first end and a second end; where the second end is opposed to the first end; a first node (122A), for example a quantum dot, that comprises a first semiconductor; where the first node contacts a radial surface of the one-dimensional semiconducting nanoparticle producing a first heterojunction at the point of contact; and a second node (122B), for example a quantum dot, that comprises a second semiconductor; where the second node contacts the radial surface of the one-dimensional semiconducting nanoparticle producing a second heterojunction at the point of contact; where the first heterojunction is compositionally different from the second heterojunction.
