“…Lead sulfide (PbS) and cadmium sulfide (CdS) are two semiconductors studied since time ago, their combined research has around one century and the direct band gap for PbS is around 0.37 eV at 300 K [1][2][3][4][5][6][7][8][9][10]. The PbS is mainly used as an infrared detector in various fields has been used mainly as an infra-red detector in another diverse field [11][12][13][14][15].…”

The goal of this chapter is to present three kind of thin films for the materials, done by Chemical Bath Deposition technique, the materials are CdS, PbS and CuS. The characterization has been diversified, but consisting mainly X-ray Diffraction (XRD) giving hexagonal, cubic and amorphous structures of CdS, PbS and CuS respectively. The Raman dispersion let to found the characteristics peaks of vibration, one for the CdS located on 300.7 cm −1 , three for PbS and two more for the CuS. We use X-rays Photoelectron Spectroscopy to formalize the chemical composition analysis, from this analysis we could to proof the high purity of the chemical bath deposition method in the materials preparation. We used UV-Vis Spectroscopy to determine simple optical responses, getting the biggest transmittances of 72% for CdS, 45% for PbS, and 80% for CuS, and direct energy band gaps of 2.47 eV for CdS, 1.78 eV for CuS as ground and with thermic annealing 2.45 eV which is believed result of amorphous to crystalline morphology changes, the indirect bandgap 0.94 eV is measured too. The AFM given information about the surface morphology and roughness, Scanning Electron Microscopy (SEM) micrography shows the polycrystallinity nature of the CuS including the smooth.

“…It's high absorbance within the UV-Vis spectral vary and high transmittance within the infrared spectral region of allowing its use in infrared detectors [2,9]. Thin film of lead sulphide is helpful within the manufacture of transistors [3], photoconductive infra-red detectors [4], windows, contact rectifiers, prisons, lenses [5], photovoltaic application in solar cells [6], solar control coating [7], optoelectronic devices [8], antireflection coatings and for solar thermal applications [9] in flat-plat collectors, house heating for solar chick brooding (11), Photo resistance, diode lasers, humidity and temperature sensors, decorative coatings and solar control coatings [12], pollution monitor [25]. Many techniques are reported for the deposition of thin films like Chemical spray deposition (CSP) [26], Molecular beam epitaxy [13], chemical vapor deposition (CVD) [15], sol-gel spin coating [16], successive ion layer absorption and reaction (SILAR) method [4], chemical bath deposition (CBD) [13] ect.…”

Nanocrystalline PbS thin films were deposited on glass substrates with various deposition times using chemical bath deposition technique. PbS thin films were prepared by using a solution of Lead nitrate and thiourea by using NaOH salt as a complexing agent and ammonia solution as a pH adjuster at 65 0 C. The study was carried out for thickness in the range of (0.16-1.03m). The structural properties were carried out by X-ray diffraction (XRD). The X-ray diffraction patterns reveal that the films exhibit the cubic face centered structure. The crystalline sizes of the films increased with increasing film thickness. The morphological properties were studied by SEM and showed that films were well adherent to the substrate, uniform, small crystal size and covered the entire substrate surface completely. The optical properties of these films have been studied and show that PbS thin films have the values of energy gap varied between (0.88-1.34 eV) with increasing film thickness.

Cobalt-Nickel alloys have been widely used for decoration, in magnetic recording devices and corrosion resistance applications, etc. In this study, the influences of cobalt amount in electrolyte on the magnetic and structural properties of the electrodeposited Co-Ni alloys were investigated. An electrolyte solution, consisting of cobalt sulfate, nickel sulfate, nickel chloride and boric acid, was used in electrodeposition. The electrochemical investigation of Co-Ni alloys was completed using cyclic voltammetry and galvanostatic studies. The morphological and structural analyses of the alloys were performed using inductively coupled plasma, scanning electron microscopy, X-ray diffraction and vibrating sample magnetometer techniques. The effect of cobalt concentration on the magnetic properties, phase structure and grain size of the alloys was investigated. Magnetic hysteresis results indicate that the amount of the cobalt content in the electrolyte has a strong influence on the ferromagnetic behavior of fabricated alloys. Results of the study show that changing the electrodeposition parameters, such as composition of electrolyte solution, allows to fabricate alloys with different properties.
