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 12h nucleation and growth of spherical CdS nanoparticles with a radius of up to 34±4Å. After the nucleation is completed after 24h, further growth in this amorphous environment is governed by oriented particle attachment mechanism as found for a liquid medium. Towards 48h the particle shape has changed into spheroidal with short and long axis of 40±2Å and 120±2Å, respectively.
