Multi-heterojunction nanoparticles, process for their production and articles containing 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; 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.
