Claim Text:
1. A semiconductor structure, comprising: a nanocrystalline core comprising a first semiconductor material; a nanocrystalline shell comprising a second, different, semiconductor material at least partially surrounding the nanocrystalline core; a first compositional transition layer disposed between, and in contact with, the nanocrystalline core and nanocrystalline shell, the first compositional transition layer having a composition intermediate to the first and second semiconductor materials; a nanocrystalline outer shell at least partially surrounding the nanocrystalline shell, the nanocrystalline outer shell comprising a third semiconductor material different from the first and second semiconductor materials; a second compositional transition layer disposed between, and in contact with, the nanocrystalline shell and the nanocrystalline outer shell, the second compositional transition layer having a composition intermediate to the second and third semiconductor materials; and an insulator coating surrounding and encapsulating the nanocrystalline core/nanocrystalline shell/nanocrystalline outer shell structure.
