Cadmium sulfide and cadmium selenide/polymer nanocomposites were prepared via in-situ radical
polymerization in a miniemulsion. Organically capped CdE (E = S, Se) quantum dots (QDs) were
used as the starting materials and ensembles of these dots were encapsulated with no need of
further surface treatment. The use of two polymer matrices was investigated: poly(styrene) (PS) and
poly(n-butyl acrylate) (PBA). In both cases, homogenous nanocomposites were obtained and their
optical properties were investigated by visible absorption and photoluminescence spectroscopy.
Quantum size effects were assigned to the nanocomposites, indicating the integrity of the individual
QDs upon polymer encapsulation using the miniemulsion process
