A facile and reliable route to prepare of flower shaped lead sulfide nanostructures from a new sulfur source

• Synthesis of thio Schiff base (C13H11NS) and its metal complex.
• Application of thio Schiff base as both ligand and sulfuring agent.
• A facile solvothermal method to synthesize PbS.
• Spectral and optical characterization of the synthesized compounds.

Flower shaped PbS nanostructures were prepared by the solvothermal method using propylene glycol and a new sulfuring agent. Novelty of this work is application of a new thio Schiff-base as complexing and sulfuring agent for synthesizing of PbS nanostructures. SEM and TEM was used to examine the surface morphology of the grown samples; also the products were characterized by XRD, SEAD, UV–vis and FT-IR spectra. The results of this paper indicate that the shape and size of lead sulfide nanocrystals can be controlled systematically by setting certain reaction parameters.
