Small angle X-ray and neutron scattering on cadmium sulfide nanoparticles in silicate glass

Small angle X-ray and neutron scattering on Cd and S doped glass annealed at 600 °C shows after the first 9 h nucleation and growth of spherical CdS nanoparticles with a radius of up to 34±4 Å. Towards 48 h the particle shape has changed into spheroidal with short and long axis of 40±2 and 120±2 Å, respectively. After the nucleation is completed after 24 h, further growth in this amorphous environment is governed by oriented particle attachment mechanism as found for a liquid medium.
