Abstract :
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 were studied. Their sizes and morphologies are expressed and their Raman spectrumare discussed. In each case, representing the reason of any Raman peak, it has been tried to be a compare them.
