Abstract:

This paper discusses the light scattering of multicomponent silicate glass doped with lead sulfide, which results from secondary heat treatment when a two-phase system consisting of a glassy matrix and a nanostructured semiconductor phase of PbS is formed. The Rayleigh–Brillouin scattering spectra are obtained in this system. It is established that the Landau–Placzek ratio monotonically increases from 170 to 850 s as the heat-treatment time is increased, because the radius of the PbS crystals in the range 2.0–2.5 nm and their concentration increase.

Keywords:

light scattering, semiconductor nanocrystals in glassy matrix, Landau–Placzek ratio
