Photoluminescent thin films with nanostructured surface

Abstract

We present here experimental results on polymer-inorganic nanocomposite material made of styrene with butyl methacrylate (SBMA) with isothiocyanato-chalcone (ITCC) and inorganic semiconductor CdS. Styrene with butyl methacrylate (1:1) copolymer has been prepared by the method of radical polymerization. The photoluminescent nanocomposites based on isothiocyanatochalcone were obtained using organic solvents instead of water according to the method described elsewhere [1,2]. Thin films with good quality can be obtained for concentrations of CdS in the range 0-20 %. The cyanato-chalcone derivate was used as mechanical additive, as well as chemical bonding in the polymer, which make it more stable. As aromatic chalcones were used n,ndimethylthiourea-chalcone and isothiocyanato-chalcone. The concentration of CdS semiconductor was varied in the range 0-20 %.
