Title: One-Pot Process in Scalable Bath for Water-Dispersed ZnS Nanocrystals with the Tailored Size

Abstract

Well-dispersed ZnS nanocrystals with tailored size in aqueous solutions were synthesized by employing cysteine-sulfur (Cys-S) complexes with low molecular weight in a scalable anoxic vessel. High yield production of water-dispersed ZnS nanocrystals on a 10-L scale was demonstrated in an aqueous solution process. The average crystallite size of ZnS was controlled by changing the ratio of the cysteine to sulfide in the applied Cys-S complexes. A decrease in the crystallite size of ZnS likely resulted in both the blue shift of peak positions and the relative variation of peak intensities in the photoluminescence properties. In addition, the pH-dependent stability against aggregation of ZnS nanocrystals was investigated to reduce agglomeration.

  • Soft-templated phosphorylated mesoporous carbons with homogeneous distributions of phosphate groups were prepared by a 'one-pot' synthesis method using mixtures of phosphoric acid with hydrochloric, or nitric acids in the presence of Pluronic F127 triblock copolymer. Adjusting the various ratios of phosphoric acid used in these mixtures resulted in carbons with distinct adsorption, structural and surface acidity properties. The pore size distributions (PSDs) from nitrogen adsorption at -196 C showed that mesoporous carbons exhibit specific surface areas as high as 551 m{sup 2}/g and mesopores as large as 13 nm. Both structural ordering of the mesopores and the final phosphate contentsmore » were strongly dependent on the ratios of H{sub 3}PO{sub 4} in the synthesis gels, as shown by transmission electron microscopy (TEM), X-ray photoelectron (XPS) and energy dispersive X-ray spectroscopy (EDS). The number of surface acid sites determined from temperature programmed desorption of ammonia (NH{sub 3}-TPD) were in the range of 0.3-1.5 mmol/g while the active surface areas are estimated to comprise 5-54% of the total surface areas. Finally, the conversion temperatures for the isopropanol dehydration were lowered by as much as 100 C by transitioning from the least acidic to the most acidic catalysts surface.« less
  • Describing the preparation of ε-Co nanocrystals coated by a monolayer of poly(acrylic acid)-block-polystyrene or PAA−PS, a method adopted from one using oleic acid as the surfactant.
  • High-quality colloidal photoluminescent CdS quantum dots (QDs) were synthesized via a noninjection onepot approach in noncoordinating solvent 1-octadecene. This synthetic approach uses cadmium acetate dihydrate and elemental sulfur as Cd and S sources, respectively, together with one long-chain fatty acid (CH3-(CH2)n-COOH) as surface ligands and 2,2 -dithiobisbenzothiazole (MBTS) to increase sulfur activity. The CdS QDs were synthesized at elevated temperatures such as 240-300 C, and the kinetics of nucleation/ growth was monitored via the temporal evolution of the optical properties of the growing CdS QDs. Various synthetic parameters were investigated, such as the feed molar ratios of (0.5-8)Cd/1S and (2-64)S/1MBTS,more » reactant concentrations of 5-80 mmol/Kg, and growth temperature of 220-350 C. The feed molar ratios of (1-2)Cd/1S and (8-32)S/1MBTS are suggested to be the optimal synthetic window, together with the S feed concentration of 10-20 mmol/Kg and the growth temperature of 240-260 C. Moreover, ligand effects such as ligand length and concentration were thoroughly investigated. With an increase of the chain length of the fatty acid, the size of the resulting CdS QDs was systematically reduced. The acids of moderate carbonchain length (n ) 10-16) bestow CdS QDs in high quality regarding narrow size distribution ( 17-22 nm in full width at half-maximum), high nanocrystal yield, and high quantum yield (up to 30%). Meanwhile, the acids with longer carbon chain led to small-sized nanocrystals in low concentration, due to large steric hindrance retarding severely the nucleation and growth, as indicated by the late appearance of nanocrystal absorption and slow increase in size. The acids with shorter carbon chain resulted in large-sized nanocrystals in low concentration, due to small steric hindrance causing ready nucleation and growth, as indicated by the large and fast increase in size. Therefore, the steric hindrance of varied-length fatty acids affects the reactivity of Cd monomers with great impacts on the nanocrystal nucleation/growth and thus the nanocrystal size and surface passivation. Furthermore, with an increase in the acid concentration, the size and size distribution of the resulting CdS QDs increased, together with a decrease in nanocrystal yield, due to an enhanced solubility of the Cd monomer leading to decreased monomer reactivity and thus a hindered nucleation with a low nuclei concentration.« less
  • Chemical-bath deposition of ZnS thin films from NH{sub 3}/NH{sub 2}-NH{sub 2}/SC(NH{sub 2}){sub 2}/ZnSO{sub 4} solutions has been studied. The effect of various process parameters on the growth and the film quality is presented. A first approach to a mechanistic interpretation of the chemical process is reported. The structural, optical, chemical, and electrical properties of the ZNS thin films deposited by this method have been studied. The electron diffraction (EDS) analysis shows that the films are microcrystalline with a cubic structure. EDS analysis has demonstrated that the films are highly stoichiometric. Scanning electron microscopy studies of the ZnS thin films depositedmore » by this method show that the films are continuous and homogeneous. Electrical conductivity measurements have shown the highly resistivity nature of these films ({sigma} = 10{sup {minus}9} S/cm).« less
