Electrodeposition of Polymer−Semiconductor Nanocomposite Films

Abstract

Hybrid polymer−semiconductor nanostructured films were obtained by co-electrodeposition of poly(vinyl acetate-co-crotonic acid) and CdS or CdTe nanoparticles (NPs) stabilized with 1-thioglycerol (TGL) or thioglycolic acid (TGA). Composite films were enriched with negatively charged NPs stabilized with TGA. Relative uptake of these NPs increased with electrodeposition time and increase in NP concentration in solution, while the variation in electric field had little effect on NP electrodeposition. No substantial aggregation or NP growth occurred in the electrodeposition process and during film formation. Electrodeposited films showed higher quality and better properties of NPs compared to the cast films obtained from the same solutions. Electrodeposition of hybrid polymer−semiconductor films on patterned substrates was demonstrated.

Electrospinning preparation and photophysical properties of one-dimensional (1D) composite nanofibers doped with erbium(III) complexes

“…1D nanostructural materials have drawn extensive interest recently due to their extensive application [12][13][14]. Electrospinning technique is a simple and low-cost method for making continuous ultrafine nanofibers with diameters ranging from tens of nanometers to several micrometers [15,16], which depends on the solvent and the solution properties [17].…”

Synthesis and Characterization of CdTe Nanoparticle/Polymer Functional Composites

“…3 Other methods such as electrochemistry, sol-gel, as well as ultrasonic irradiation are also employed to prepare the NP/polymer composites. [4][5][6] By using these methods, composites with * Authors to whom correspondence should be addressed. the advantages such as the improved long-term stability, good processability as well as the very limited Förster resonance energy transfer (FRET) between NPs due to site isolation by polymer chains are prepared.…”

Hybrid nanocomposites based on CdS and CdSe colloidal nanocrystals in organic polymers

“…Such synergism provides excellent opportunities to fabricate original materials, showing promising applications in light-emitting diodes, optical switches, optical fibers, and hard transparent coatings used as protective layers or sensors. 1 Inorganic NCs of different nature and size can be dispersed in optical transparent polymer as polystyrene (PS) and poly(methyl methacrylate) (PMMA). These polymers offer low cost, processability, and possibility of functionalization, while II-VI semiconductor NCs show size-dependent band gap shift, excitonic photoluminescence, electroluminescence, and nonlinear optical properties.…”
