Synthesis and structural studies of hexadecylamine capped lead sulfide nanoparticles from dithiocarbamate complexes single source precursors

• PbS nanoparticles synthesized from dithiocarbamates complexes.
• The optical properties of the nanoparticles show blueshifts and broad emission.
• The PbS nanoparticles were indexed to the cubic rock crystalline phase.
• The crystallite sizes are 5–16 nm.

We report the synthesis of lead sulfide (PbS) nanoparticles from Pb(II) alkyldithiocarbamate at 200 °C. The absorption spectra of the PbS nanoparticles are blueshifted and they also showed broad emission. The powder XRD of the PbS nanoparticles was indexed to the cubic rock phase with estimated crystallite sizes of 14–19 nm. The TEM images of the nanoparticles showed particles with spherical and rectangular shapes with average crystallite sizes of 5–16 nm.
