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; a first endcap (108) contacting one or both of the first end or the second end; where the first endcap comprises a first semiconductor and where the first endcap extends from the one-dimensional nanoparticle to form a first nanocrystal heterojunction; and a second endcap (110) that contacts the at least one first endcap; where the second endcap comprises a second semiconductor and where the second endcap extends from the first endcap to form a second nanocrystal heterojunction; and where the first semiconductor is different from the second semiconductor.

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.
