| The process of miniemulsion polymerization permits the encapsulation of quantum particles into a polymer matrix providing them of chemical stability without affecting their luminescent properties. In this work, the synthesis process was conducted varying levels of surfactant, initiator and CdSe QDs. A microscopy study on the composite latexes and later a statistical analysis indicated that the increment in surfactant concentration produced a decrease in the polymer particle size, which increased in turn the rate of polymerization and percentage conversion. The obtained latexes were stable and showed fluorescence by excitation with UV light. The spectrofluorometry studies indicated that in composite latexes the fluorescence was a function of polymer particle size and the amount of encapsulated dots per polymer particle. | |
