The Shape of Se-Precipitates in a CdSxSe1−x-Doped Glass
Small angle neutron scattering (SANS) experiments have been carried out on a semiconductor-doped glass in order to determine the average size and shape of CdSxSe1−x precipitates (x ≈ 0.7). The crystallites are of spherical shape with a mean radius of Rp = 3.5 ± 0.1 nm and are rather monodisperse. The polydispersity is lower than ΔR/Rp ∼0.1. Approximately 69% of CdSxSe1−x are bound in the precipitates, the rest is dissolved in the glass matrix.
