Lead sulfide (PbS) nanostructures are one of the possible candidates to be used in modern optic devices. It can be deposited by various methods. Composition of the deposited layers and their optical properties can be determined by Raman spectroscopy. In this work, Raman features of PbS nanostructures are discussed in detail. Several different morphology of PbS nanostructures such as nonocubics, hexapod and octahedron was studied. Their size and morphologies are expressed and discussed about their Raman spectrum. In each case, represented the reason of the any Raman peaks and finally, it has been tried to be a comparison between them.
