cd1-xmnxs (x = 0, 0.1, 0.2) nanoparticles, prepared by co-precipitation method under ultrasonic irradiation, were studied by means of x-ray diffraction, scanning electron microscopy, ftir and uv-vis  spectroscopy measurements. the average particle size of nanoparticles from the scanning electron microscopy image is about 20-30 nm. results show that partial substitution of cd by mn leads to a re...

Large scale high yield cadmium sulfide (CdS) nanowires with uniform diameter were synthesized using a rapid and simple solvo-chemical and hydrothermal route assisted by the surfactant cetyltrimethylammonium bromide (CTAB). Unique CdS nanowires of different morphologies could be selectively produced by only varying the concentration of CTAB in the reaction system with cadmium acetate, sulfur pow...

2014 Photovoltaic devices have been obtained by a direct polymerization of undoped (or p-type doped) thin film (CH)x layer onto a polycrystalline cadmium sulfide film. The morphology of the contact is observed by S.E.M. microscopy. The electrical characteristics of this device are studied in the dark or under illumination. The main result, at AM1, 100 mW/cm2 with doped (CH)x correspond to 0.5 p...

Thin and transparent films of doped cadmium sulfide (CdS) were obtained on commercial glass substrates by Chemical Bath Deposition (CBD) technique. The films were doped with low concentration of Sn, and annealed in air at 300 °C for 45 min. The morphological characterization of the films with different amounts of dopant was made using SEM and EDAX analysis. Optical properties of the films were ...

The Chah-Shaljami polymetal ore deposit contains heavy metal anomalies in various mineralization zones. Geochemical distribution and correlation of elements in surficial soilsindicate that sulfide, sulfate, sulfosalt and silicate mineral occurrences (e.g. Pyrite, chalcopyrite, galena, sphalerite, molybdenite, enargite, hornblend and biotite) in mineralization and stockwork zones resulted in the...

Size-controlled cadmium sulfide nanoparticles were successfully synthesized by immobilized Rhodobacter sphaeroides in the study. The dynamic process that Cd(2+) was transported from solution into cell by living R. sphaeroides was characterized by transmission electron microscopy (TEM). Culture time, as an important physiological parameter for R. sphaeroides growth, could significantly control t...

Nowadays efficient down conversion for white light emission is mainly based on rare-earth doped phosphors or cadmium-containing quantum dots. Although they exhibit high luminescence efficiency, the rare-earth mining and cadmium pollution have so far led to extremely high environmental cost, which conflicts the original purpose of pursuing efficient lighting. Here, we explore a new strategy to a...

Alkaline phosphatase (ALP) activity was detected using bovine serum albumin (BSA)-functionalized manganese-doped zinc sulfide (Mn–ZnS) quantum dots (QDs), and the phosphate substrate vitamin-B 6 cofactor pyridoxal 5′-phosphate (PLP).

Cadmium sulfide uniform fine particles have been synthesized in soft conditions, at room temperature, using cadmium complex compounds and thioacetamide. The microstructure and morphology of cadmium sulfide were characterized by X ray Diffraction, Transmission Electron Microscopy, High Resolution Transmission Electron Microscopy, and Selected Area Electron Diffraction. The optical properties of ...
