Abstract
The nucleation of CdS particles on the surface of polystyrene supports from aqueous ammonia—thiourea solutions was studied. The increment in the mass of nanoparticles on the support with time was determined. The degree of binding of Cd(II) ions into sulfide on the surface (support area 14 cm2, solution volume 3.7 cm3) after 3 h at 50°C was 2.2% of their total amount. The results agreed well with those of model calculations for spherical (for small times) and ellipsoid particles at a constant surface concentration. The nanoparticles that formed in solution were not involved in the formation of surface films on polystyrene supports. The photoluminescent properties of the obtained films were studied.
