X-ray diffraction and electron microscopy data show the crystal lattice structure and rod-like shape of SbSI nanocrystals obtained by ball milling to be similar to that of the bulk crystals. The dependence of the grain size on the milling duration is considered in view of the chain-like crystalline structure of SbSI. The observed Raman line broadening is discussed in the frame of confinement-related selection rules relaxation and scattering by surface phonons.
