Abstract
Polystyrene (PS) embedded ZnS QDs were prepared via thermolysis of the single source precursor, zincpyrrolidinedithiocarbamate (ZnPDTC). The in situ growth of 4–6 nm QDs was realized by thermaltreatment at 375°C and 475 °C at different durations, chosen to represent the rubbery and molten stateof the polymer matrix. The morphology of the PS/ZnPDTC nanocomposite film was evaluated using AFM.The growth kinetics was found to be faster at the polymer's molten state compared to its rubbery state.
