“…During the synthesis of precursor-4, where zinc acetate, and urea were used, there seems to be hydrolysis of zinc acetate [48]. The effect of anions during the homogeneous precipitation has been studied by various authors [49][50][51][52][53]. It is proposed that the various counter ions (chloride, nitrate, sulfate, and acetate) behave as surface modifiers.…”

“…Similar spherulitic morphology for ZnS was obtained by homogeneous precipitation from acidic zinc salt solutions. 14 The solution speciation in all experiments was computed by the HYDRAQL program, from the pH, the total mass balance, the ion pair formation for zinc and sulfur, and the electroneutrality conditions. 15,16 The activity coefficients were calculated from the extended Debye-Hü ckel equation corrected for ion interactions.…”

ABSTRACT:The combination of inorganic salts and macromolecules leads to supramolecular structures with new interesting physical and chemical properties. The deposition of ZnS (Wurtzite) on oxadiazole-terpyridine copolymer P-90/10 synthesized by free radical copolymerization were investigated. The apparent order of the crystallization process was found to be 2 that indicated a surface diffusioncontrolled mechanism. Critical nucleus formation proceeds via complexation of the ZnS molecules to the ONO atoms as concluded from computational chemistry calculations. The number of ions forming the critical nucleus was found experimentally to be (n* exp ϭ 1.71 Ϯ 0.24) in accordance with the computational chemistry calculations by the PM3 method of the MOPAC program package. The surface energy of the growing ZnS phase was found to be 121 mJ/m 2 typical for sparingly soluble salts.

“…The growth of ZnS films by CBD is generally considered to proceed by the cluster-bycluster mechanism, with colloidal ZnS aggregating both in solution and on the substrate [7][8][9].…”

“…This mechanism was thoroughly reviewed and demonstrated by Bogush and Zukoski [10,11] for the synthesis of silica particles, and has since been observed in the synthesis of ZnS powders and films [7,8]. Though less common, there are also reports of ion-by-ion growth of ZnS films, which occurs upon direct interaction between surface sites and precursor species (containing Zn 2+ and S 2-) [12,13].…”

Morphology and growth behavior of O2-free chemical bath deposited ZnS thin films

We investigate the role of reagent concentrations and ambient O 2 on the morphology and growth behavior of ZnS thin films grown with the chemical bath deposition method. We investigate the role of substrate on film morphology, and find significant differences between films deposited on SiO 2 versus Si. The films are also sensitive to dissolved O 2 in the bath, as it causes a layer of SiO 2 to form at the ZnS/Si interface during deposition. Degassing of solutions and an N 2 atmosphere are effective to minimize this oxidation, allowing deposition of ZnS films directly onto Si. Under these conditions, we examine film properties as they relate to reagent bath concentrations. As the reagent concentrations are decreased, both the film roughness and growth rate decrease linearly. We also observe deformation and shifting of x-ray diffraction peaks that increases with decreasing reagent concentrations. The shifts are characteristic of lattice compression (caused by the substitution of oxygen for sulfur), and the deformation is characteristic of distortion of the A C C E P T E D M A N U S C R I P T ACCEPTED MANUSCRIPTARTICLE Thin Solid Films 2 lattice near crystal grain interfaces (caused by tensile stress from interatomic forces between neighboring crystal grains). At the weakest concentrations, the low roughness suggests a mixed growth mode in which both clusters and individual ZnS nanocrystallites contribute to film growth. With increasing reagent concentrations, the growth mode shifts and becomes dominated by deposition of clusters.
