Insight into co-operative growth of nearly monodispersive CdS nanocrystals embedded in polyvinyl pyrrolidone

Abstract: Nanocomposites of CdS nanocrystals (NCs) embedded in a polyvinyl pyrrolidone are grown using onestep chemical bath deposition technique. While this method eliminates an additional step for the growth of NCs, it also leads to the formation of nearly monodispersive CdS NCs as indicated by absorption, reflection, and photoluminescence spectroscopy. Further, scanning electron microscopy, energy-dispersive spectroscopy, and transmission electron microscopic investigations reveal the formation of nearly monodispersi… Show more

“…The continual effort of researchers worldwide further suggests that the shape/morphology of the nanocatalyst is also crucial for obtaining the desired performances . Morphology-dependent fascinating spectroscopic signals and properties, such as biosensor applications of 3D stone-like Cu 3 TeO 6 , have also been discerned. Among various possible morphologies, the large surface area and rapid electron reaction kinetics of 1D nanostructures have been the subject of intense research in terms of both fundamental interest and applications in varied fields.…”

“…Despite the widespread use of PVP in various fields, their properties require further improvements to achieve a much wider range of applications. This polymer because of its long chain network dissolved metal salts and pyrrolidone groups which complex with many inorganic salts resulting in fine dispersion has been commonly used for the preparation of nanocomposites (NCs) …”

“…[6][7][8] The incorporation of nanometer-scale filler particles into a polymer matrix can enhance various mechanical and thermal properties of the resulting NCs compared with the pure polymer. 9 There are several kinds of nanofiller which have been used for preparation of NCs but among them, metal oxides because of their characteristics such as optical, electronic, mechanical, and structural are a good candidate for fabrication of NCs.…”
