Abstract

We report the colloidal synthesis of monodisperse nanocrystals (NCs) of InSb, which is an important member of III-V semiconductor family. Colloidal InSb NC quantum dots showed well-resolved excitonic transitions in the near-infrared spectral range, with the optical band gaps tunable from ∼1.03 eV (1200 nm) to ∼0.71 eV (1750 nm) corresponding to 3.3 and 6.5 nm InSb NCs, respectively. We observed size-tunable band edge photoluminescence that could be significantly enhanced by growing InSb/CdSe or InSb/CdS core-shell nanostructures. Films of InSb NCs capped with S2- ions showed ambipolar charge transport.
