Synthesis and Characterization of Cadmium Sulfide Obtained at Room Temperature

2010

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 the samples were examined by UV – Visible spectroscopy.

Preparation and characterization of Cu and Ni sulfides nanoparticles

In the present work we aimed to prepare two metal sulfides nanoparticles [copper monosulfide (CuS) and nickel monosulfide (NiS)] using two different sulfur sources (Potassium N 0-[4-(N 0-dithiocarboxy-hydra zino)-4-oxo-butyryl]-hydrazine carbodithionate (I) and thiourea (II)) by a simple chemical method in an aqueous ethanolic solution. The effect of the used sulfur source on the optical and structural properties of the prepared metal sulfides was investigated. The synthesized sulfides were characterized using X-ray diffraction (XRD), UV-visible spectrophotometry, Transmission Electron Microscope (TEM) and elemental analysis. The yield, lattice parameters, crystallite sizes, microstrains and the band gap energy of the prepared CuS and NiS nanoparticles were evaluated and compared. Using the organic salt (I) leads to obtaining single phase structure of CuS and NiS, while using thiourea lead to obtaining mixed phases structure. By using the organic salt (I) we obtained CuS nanoparticles having greater potential for solar cell applications and NiS nanoparticles very interesting for photo catalysis applications.
