Abstract

Abstract: The dodecyl vinylbenzyldimethylammonium chloride was synthesized, which was subsequently encapsulated with CdTe quantum dot via electrostatic reaction and bulk free radically copolymerized with styrene. The structure and optical properties of the obtained copolymer polystyrene/CdTe was investigated using fourier transform infrared spectroscopy (FT-IR), transmission electron microscopy (TEM), scan electron microscopy (SEM), UV-visible absorption spectrum, and fluorescence spectrum. The polystyrene/CdTe composites emitted green light under ultraviolet and visible region (380~480 nm). When the content of CdTe quantum dot bearing monomer was 1.2 wt %, the luminescence quantum yield of polystyrene/CdTe was 9.6 %.

Key words: cadmium telluride, polystyrene, composite, quantum dot, luminescence property
