Nano Cd0.9Mg0.05S was synthesized applying the thermolysis technique in air and under flow of nitrogen. Samples obtained exhibited CdS structure with two phases. Rietveld refinement analysis used to determine different parameters. Analysis UV–Vis absorption spectra disclosed that optical band gap sample prepared N2 is less than corresponding air. The (air) decreased as it doped Mg while increas...

CuInS2 (CIS) quantum dots (QDs) have tunable photoluminescence (PL) behaviors in the visible and near infrared spectral range with markedly lower toxicity than the cadmium-based counterparts, making them very promising applications in light emitting and solar harvesting. However, there still remain material- and fabrication- related obstacles in realizing the high-performance CIS-based QDs with...

We report an inexpensive TiO2 based quantum dot solar cell (QDSSC) with improved power conversion efficiency prepared by simple techniques. Barium doped zinc sulfide has been successfully deposited on cadmium dots (QDs) successive ion layer adsorption and reaction (SILAR) technique. The is utilized as a passivation in the QDSSC, which helped better charge separation. copper (Cu2S) reduced graph...

Cadmium is a hazardous heavy metal existing ubiquitously in the environment, but the mechanism of cadmium transport into mammalian cells has been poorly understood. Recently, we have established a cadmium-resistant cell line (Cd-rB5) from immortalized metallothionein-null mouse cells, and found that Cd-rB5 cells exhibited a marked decrease in cadmium uptake. To investigate the mechanism of alte...

highly crystalline bi3+-doped cadmium oxide (cdo) sub-micron structures were synthesized by calcination the obtained precursor from a sol-gel reaction. the reaction was carried out with cadmium nitrate (cd(no3)2.4h2o), bismuth nitrate (bi(no3)3.5h2o) and ethylene glycol (c2h6o2) reactants without any additives at 80°c for 2h. resulting gel was calcined at 900 °c with increasing temperature rate...

Cu doped CdS nanophosphors were fabricated through Langmuir-Blodgett route for the first time. Precursors mixed Langmuir-Blodgett multilayers of cadmium arachidate-copper arachidate were used to grow doped sulfide nanoparticles within the organic matrix through postdeposition treatment with H(2)S gas. Changes in composition and layered structure of precursor multilayers were studied using Fouri...

Cadmium sulfide particles were prepared by precipitation from acid solution. A radiotracer technique with 109Cd was applied tomeasure the solubili W of cadmium sulfide at various pH's. Filtration, centrifugation, ulttacentrifugation, and dialysis were used to separate the particles from the solution. Only the last two techniques proved to be successful. The solubility of cadmium sulfide in wate...

The cadmium sulfide nanoparticles were synthesized from the nickel-cadmium cake of a hydrometallurgical zinc producing plant and sodium sulfide as Cd2+ and S-2 sources, respectively. Also, the synthesis process was performed by using the secretions of Bacillus licheniformis as bio-surfactant. Initially, in order to obtain a cadmium rich solution, two following steps were carried out: 1) Alkalin...
