Direct synthesis of II–VI compound nanocrystals in polymer matrix

Abstract

Abstract The production of II–VI semiconductor compound – polymer matrix nanocomposites by a direct in‐situ thermolysis process is described. Metal‐thiolate precursor molecules embedded in a polymer matrix decompose by a thermal annealing and the nucleation of semiconductor nanocrystals occurs. It is shown that the nucleation of nanoparticles and the formation of the nanocomposite can be also achieved by laser beam irradiation; this opens the way towards a “lithographic” in‐situ nanocomposite production process. A possible growth and nanocomposite formation mechanism, describing the structural and chemical transformation of the precursor molecules, their decomposition and the formation of the nanoparticles, is presented.
