Blend Composites Based on Polystyrene–CdSe Quantum Dots and Polystyrene–Gold Nanoparticles Hybrid Systems

Polystyrenes of different molecular masses are synthesized by controlled radical polymerization via the reversible addition fragmentation chain transfer mechanism. The resulting polymers are used for designing nanocomposites based on cadmium selenide quantum dots and gold nanoparticles. It is demons...

Description
Summary:Polystyrenes of different molecular masses are synthesized by controlled radical polymerization via the reversible addition fragmentation chain transfer mechanism. The resulting polymers are used for designing nanocomposites based on cadmium selenide quantum dots and gold nanoparticles. It is demonstrated that the photoluminescence of quantum dots in the sol grows appreciably during continuous irradiation for 5–6 h but is reduced during the “light switching off–switching on” process. It is shown that, upon the addition of gold nanoparticles, the photoluminescence of quantum dots in the sols changes insignificantly.
