“…However, its volatility and toxicity have contributed to a search for other materials. Among them, are ethylene-diamine (ED) [6], ethylenediaminetetraacetic acid (EDTA) [6], polyethyleneimine [7], acetylacetone [8] and glycine [9]. There are only a handful of complexing agents proposed and few studies on the interactions involved between complexing agents and CdS.…”

“…Our aim is to propose new com-plexing agents that can show a good affinity with CdS to enhance the homogeneity of the morphology and structure of the film. We propose citrate ion as a complexing agent for CdS based on our previous studies [9,10] that show a high relationship between the stability of CdS and an oxygen-rich complexing agent. The main goal of this paper is to analyze the participation of the oxygens in the citrate ion on the interaction between it and Cd 2+ /CdS through charges, delocalization indices, HOMO/LUMO and absolute electronegativity.…”

Theoretical studies on conformational analysis, geometry optimizations and frequencies for citrate at the MP2/LAN-L2DZ level portrait it as a promising candidate for a complexing agent for cadmium (II) ion (Cd 2+) and cadmium sulfide (CdS). Natural Bond Orbital (NBO) charges, Delocalization Indices, HOMO/LUMO gaps and surfaces along with absolute electronegativity values were employed to analyze the interactions among the configurations obtained. The most stable structures involved the interaction between the LUMO of Cd 2+ /CdS and the most dense region of the HOMO of the citrate ion.

This work focused on comparing cadmium sulphide (CdS) thin films with and without CdS silver aggregates (CdS:Ag) deposited on the surface. We report absorption and transmission responses. Using the Tauc method, we obtained direct band gap energies with values of 2.50 (CdS) and 2.49 eV (CdS:Ag). We performed a scanning electron microscope characterization at different magnifications were cluster formations with granular shapes were observed. The highest magnification of 50,000× showed silver clusters as shiny granulates, which were confirmed by microprobe elemental mapping at a magnification of 18,000×. Energy Dispersive Spectroscopy revealed that the light composition of the silver clusters was the unique difference from the CdS thin film. X-Ray Diffraction results only detected the hexagonal CdS pattern, but not that of silver. The crystallite size was of around 13 nm. A Surface-Enhanced Ramman Scattering effect was observed upon the silver coating of the CdS thin film at 293.3 cm–1.
