“…All the reagents used in this experiment were analytical grade (Sigma-Aldrich). The ITO substrates were cleaned as reported in our previous work [8]. Following a thorough cleaning with a cotton-bud and soap solution, the substrates were rinsed under running water and ultrasonically treated with distilled water, acetone, and methanol for 10 minutes each at a temperature of 40 o C. After cleaning, the substrates were dried at a moderate temperature in an open furnace.…”

The tuning of optical and dielectric parameters, structural and microstructural properties of CdO synthesized via a solution growth two-electrode cell arrangement under ambient environment, with the incorporation of Co ion into its matrix was investigated. The energy band gaps of the films was estimated in the range of 1.69 eV</=Eg</= 1.96 eV. The extinction coefficient, k for all the samples decreases as the incident photon energy increases. The films exhibit considerably high optical conduction across the photon energy with estimated power of 1013 (Omega m)-1. The elemental composition of the samples was determined using the energy dispersive x-ray spectrometry technique. The micrograph images from scanning electron microscopy technique shown that the films are polycrystalline and well-adhered to the substrates with their crystal grains evenly dispersed across the substrates’ surface. The x-ray diffraction analysis confirmed that the deposited films are of polycrystalline in nature. The films show preference for orientation along the (111) plane.

“…The increase was attributed to an increase of the defects in the thick film. It also implies that there exists a localized state in the energy band gap [9]. Urbach energy therefore represents the degree of disorder and defects [12] and it corresponds to the band tail width of the localized states in the energy gap [7].…”

“…Several deposition techniques have been used to growth binary chalcogenide [8] among them being CBD which was used PbS in this study and whose results is presented for which its optical properties are reported within UV, Visible, and near infrared region (NIR) of radiation. Mathematical approaches were also used analyze its optical properties in order compare the experimental and theoretical analysis in related studies elsewhere [5,[9][10][11][12][13]. This study examined the influence of a pair of electrons from a nitrito-group ligand on the optical properties of binary PbS thin films grown by solution technique.…”

In general, thick and thin films are developed to provide special properties that range from electrical properties, optical, mechanical and chemical properties that can satisfy the needs for specific applications in technology. Lead sulfide (PbS) is an example of such films. Lead sulfide thin films have been synthesized on glass substrates. Some of the advantages of PbS thin film in olar cell applications include low material consumption, shorter energy payback period, large area modules, monolithic integration, tuneable material properties, low-temperature processes, and transparent modules. PbS thin films help also help in preventing corrosion of metallic parts of many devices. They are also used to offer protection against wear in moving parts. Materials such as jewelry, wrist watches, and knives are often coated to avoid corrosion. For deposition of PbS thin films, lead acetate is used as lead precursor and for sulfur source thiourea, has been was used in many studies.in this study, three samples of lead sulphide thick films were deposited on microscope glass slides at varying nitrito-group ligand concentrations at room temperature using solution method. The nitrito group ligand has a capacity to coordinate a central metal {Pb) atom using two different sites. First, it can use the nitrogen (N) atom as donor atom (nitrito group) and the oxygen (O) as donor atom (nitrito group). Secondly, it can use a sulphur (S) atom as donor atom ( in a thiocyanate group) and nitrogen (N) atom as donor atom ( as in a isothiocyanate). The influence of nitrito-group ligand on the solid-State properties of PbS thin films deposited by chemical bath technique were investigated and characterized using UV-VIS spectrophotometer and Four-Point Probe (FPP) technique. They were analyzed graphically, and the results show that, the donated pair of electrons from the nitrito group ligand caused absorption edge to decreases towards longer wavelength region while band gap energy increase from 1.61eV to 3.71eV with increase concentration. On the sampled films, there was a consistent increase in the sheet resistance and electrical conductivity as the concentration of Nitrito-group ligand increases.
