Abstract

High quality luminescent CdS and CdSe nanocrystals, with tuneable band edge emission, were synthesized by means of thermal decomposition of precursors in organic solvents, incorporated in polystyrene and poly(methyl methacrylate) and deposited by casting, yielding optically transparent luminescent films. The obtained nanocomposite films were characterized by spectroscopical (UV-vis absorption and emission) and structural (TEM analysis) techniques. The effect of NC composition, concentration, size, and surface chemistry was evaluated in order to understand the role played by such factors in the nanocomposite optical properties for both the investigated polymers. The presence of organic ligand shell was demonstrated to be critical for the NCs incorporation into the polymer matrix.
