“…The TiO 2 films were sintered 450 • C for 30 min. In order to form PbS Q dots on porous TiO 2 films, successive ionic layer adsorption and reaction (SILAR) method was used [12,16,19,20]. This is the most common method for in situ synthesis of the Q dots in the porous TiO 2 substrate [4,12,16,19,20].…”

“…Chemical bath deposition (CBD) is one such simple route to grow NCs and NCps [4,7,11,23,29,30]. Most of the literature show that the NCps are grown using two-step growth process, wherein NCs capped by polymer (grown separately: first step) are embedded in polymer matrix (second step) and show band edge [4,7,11,23,29,30]. In this work, we report systematic study of one-step growth of CdS-PVP NCp using CBD technique, wherein, CdS NCs and PVP matrix are being grown simultaneously [31].…”

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 monodispersive CdS NCs (*6 to 10 nm) embedded in PVP spheres of sizes *100 to 600 nm. Systematic study of variation in Cadmium acetate (Cd ion source), Thiourea (S ion source), PVP concentration, deposition time, and heating/cooling cycles elucidates the co-operative growth mechanism for CdS-PVP nanocomposite. The experimental observations of this study are corroborated with existing theoretical simulations for nanocomposite growth, which explicates that collapse of PVP into a sphere is crucial to inclusion of only nearly monodispersive CdS NCs. Important insights obtained from this work give control on the growth of nearly monodispersive CdS NCs embedded in PVP, using a simple and inexpensive growth technique.
