Optical and Structural Properties of TOPO/HDA Capped CuS Nanocrystals via Thermal Decomposition of Bis(N-Diisopropyldithiocarbamate)Cu(II) Complex

Abstract

We present the rational synthesis of novel nanocrystals CuS (nc-CuS) by single source molecular precursor (SSMP) method. Among the present materials synthetic routes, the SSMP route is high efficient and comfortable way to construct nanostructured materials. Both CuS nanocrystals capped with hexadecylamine (HDA) and trioctylphosphine oxide (TOPO) have been synthesized by thermolysing bis (N-diisopropyldithiocarbamate)Cu (II) complex at 180 °C. Various physicochemical characterizations such as SEM images of nc-CuS exhibited uniform exfoliated surface morphologies with uniform continuous network of about 50 μm agglomerated particles. Our method could be broadly applicable for the preparation of other high quality yield metal sulfide nanostructures
