Abstract

Luminescent quantum dots of semiconductors (QD), with a configurable region in which they are synthesized and
converted into molecules, are synthesized by molecular precursors forming transparent polymethylmetha crylate and synthesized polystyrene nanocomposites. The optical properties of the obtained nanocomposites samples were studied by spectroscopic methods. Modification of the surface of QDs by variation of surface ligands has demon strated the possibility of improving luminescent properties. An attempt was made to clarify the role of surface stabilizers and shells in increasing the quantum yield
of luminescence. Optical measurements have shown effective interaction between ligand molecules and polymers.
