Abstract

Zinc blende (ZB) structure InSe nanocrystals (NCs) doped with transition metals have been synthesized via a simple and facile synthetic route. Pure ZB InSe NCs are nanosheets, while InSe:Fe are nanoparticles 6–7 nm in size and InSe:Co are 10 nm nanoworms. Doped transition metal ions have an important influence on the shape and size of produced NCs, and the influence mainly occurs at the nucleation stage for the formation of NCs. Doped ZB-InSe NCs exhibit ferromagnetism, in particular, room-temperature ferromagnetic behavior for InSe:Co NCs was observed. This is the observation of magnetism in III–VI semiconductors. The doped metal ions and the induced defects are responsible for the generated ferromagnetism in doped ZB-InSe NCs.
