TL;DR: In this article, the performance of thin films of cadmium sulfide (CdS) on glass and SnO[sub 2]:F/glass substrates from an aqueous solution containing Cadmium acetate, ammonia, ammoniumacetate, and thiourea has been investigated.
Abstract: This paper reports on thin films of cadmium sulfide (CdS) which have major applications in optoelectronic devices. Several techniques have been developed for the deposition of CdS films. Among these, growth of CdS films from an aqueous solution is the low-cost technique suitable for many applications. In this work, the deposition of device quality CdS films on glass and SnO[sub 2]:F/glass substrates from an aqueous solution containing cadmium acetate, ammonia, ammonium acetate, and thiourea has been investigated. The structural and electrical properties of CdS films have been characterized. The doping of CdS films with boron and the properties of boron-doped CdS films have also been studied. High efficiency thin film CdS/CdTe solar cells have been prepared from solution-grown CdS films.

TL;DR: In this paper, the influence of the chemical bath composition on the photocurrent response, film morphology and optical transmittance of chemically deposited CdS thin films was reported, and the optimum concentration of the bath for getting good-quality photosensitive films with good optical transmission was identified.
Abstract: The influence of the chemical bath composition on the photocurrent response, film morphology and optical transmittance of chemically deposited CdS thin films is reported. The bath parameters such as concentrations of triethanolamine, thiourea, ammonia and cadmium acetate and the bath temperature controlled the photosensitivity, photocurrent decay, morphology and optical transmittance of the films. The optimum concentration of the bath for getting good-quality photosensitive films with good optical transmittance was identified in this investigation.

TL;DR: It is demonstrated that cadmium-induced metallothionein binds zinc in the trophoblast, making this essential element less available to the fetal circulation.

TL;DR: In this article, the preparation of semiconductor dots with high number density and narrow particle size distribution, which are essential for high nonlinearity susceptibility, has been studied on CdS dispersed soda-borosilicate glasses by the sol-gel process using tetramethoxysilane (TMOS), triethylborate (B(OEt)3), sodium acetate (NaOAc), and cadmium acetate(Cd(OAc)2) as the starting materials.
Abstract: The preparation of semiconductor dots with high number density and narrow particle size distribution, which are essential for high nonlinearity susceptibility, has been studied on CdS dispersed soda-borosilicate glasses by the sol-gel process using tetramethoxysilane (TMOS), triethylborate (B(OEt)3), sodium acetate (NaOAc) and cadmium acetate (Cd(OAc)2) as the starting materials. Both number density and particle size distribution of the CdS crystallites were dependent upon the treatment conditions in the conversion of Cd(OAc)2 to CdO and CdO to CdS inside the porous gel. The optimum heat-treatment temperature for the conversion of Cd(OAc)2 to CdO was around 400 degree(s)C, and that for the conversion of CdO and CdS by exposing the gel to H2S was around 120 degree(s)C. Glass containing about 10 wt% CdS crystallites 4 - 7 nm in diameter was obtained by sintering the gel at 590 degree(s)C under the above treatment conditions.

TL;DR: Although the analysis of the metal burden in some organs seems to suggest a light increase of the cadmium level in the liver, this change has no significance at a statistical level.
