In this study, a series of PbS polyhedra were synthesized through hydrothermal decomposition of the as‐formed lead diethyldithiocarbamate (Pb‐DDTC) single‐source precursor in its precursor solution. Through extensive experiments, it was concluded that the amount of poly‐(vinylpyrrolidone) (PVP), DDTC and the reaction time had major effects on the shapes of the as‐synthesized PbS crystals. Sub‐micro sized cuboctahedrons and cubes were selectively obtained by manipulating the concentration of PVP and the reaction time. Possible growth mechanism for the shape controlled synthesis of PbS crystals was briefly discussed.
