Abstract: The microstructure and crystal structure of nanocrystalline powders and nanostructured films of lead sulfide PbS have been investigated using X-ray diffraction and electron microscopy. It has been found that, in the synthesized nanopowders, the average size of PbS nanoparticles ranges from 20 to 8 nm, whereas the average size of PbS nanoparticles in nanofilms varies from 80 to 40 nm. It has been shown that the nanocrystalline PbS powders have a cubic (space group $Fm\bar3m$) structure of the $B1$ type. The nanostructured PbS films prepared by chemical precipitation on a glass substrate have a cubic (space group $Fm\bar3m$) structure of the $D0_3$ type with the S atoms located in positions of two types: 4$(b)$ and 8$(c)$.
