Preparation and Optical Properties of CdS/PVK Nanocomposites Based on CdS Nanorod Arrays

Abstract:

Well-defined CdS nanorod arrays were pepared via a facile one-step hydrothermal approach and Poly (N-vinyl carbazole) (PVK)/CdS nanocomposites were fabricated by spin-coating chloroform solution of PVK on the surface of CdS film. A variety of techniques including scanning electron microscopy (SEM), optical absorption and photoluminescence (PL) were employed to investigate the surface morphology and optical properties of PVK/CdS nanocomposites. Photoluminescence efficiency of nanocomposites decreases compared to pure PVK and CdS nanorod arrays due to quenching through high photocharge generation quantum efficiency and high charge transport between inorganic semiconductor and conducting polymer.
