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.
