“…Annealing leads to sharp absorption edge because the films becomes more crystalline and the grain size increase with increase annealing temperature. These values are in good agreement with the values reported by others [25,26]. Figure 5 show the decrease in energy gap with increasing annealing temperature.…”

Cadmium Sulphide (CdS) thin films were grown on glass substrates by the vacuum evaporation technique. The effect of thermal annealing on the structural and optical properties of the as deposited samples was analyzed. Structure of these films was characterized by X-ray diffraction. CdS films deposited have polycrystalline structure cubic(zinc blende) and hexagonal (demand). The grain size increases with increasing annealing temperature. The optical properties of CdS films have highly transmittance in visible region of spectrum and reach to more than 84% . Band gap decreases from 2.55 to 2.33 eV with the increasing annealing temperature from 473K to 623 K.

“…The thickness of the deposited layers may be readily controlled by variation of the deposition time making the process suitable for large area processing at low fabrication cost. Although CBD has been widely used by many researchers to deposit thin films of CdO, primarily cadmium chloride [19,20,22,23] and cadmium sulfate [24,25] have been used as a source of cations. This always introduces the possibility of chlorine and sulfur incorporation into the films.…”

Cadmium oxide (CdO) thin films were grown on glass substrates by chemical bath deposition (CBD) method for different deposition times using cadmium acetate as cationic precursor. The structural and optical characterization was carried out using XRD, TEM, and UV-Vis spectrophotometer measurements. Structural analyses with XRD confirmed cubic structure of the CdO. Average particle size estimated from Rietveld refinement method of XRD pattern corresponded well with TEM measurement. The optical band gap varied between 2.35 eV to 2.48 eV with deposition time and an increase in optical band gap with decreasing film thickness was observed. The AC electrical conduction behavior of the CdO film was investigated as a function of temperature as well as frequency. The conductivity measurements indicated localized conduction and hopping of carriers between localized states. The value of real part of dielectric constant was found to decrease with frequency and increase with temperature. The Nyquist plots at different temperatures showed the existence of both grains and grain boundaries contributing to conduction mechanism.

“…The diffracted peaks at (100), (111), (200), (220), (222) and (311) are directly matched from CdO indices (JCPDS No. 05-0640) 31–33 . Crystalline and face-centred cubic structure are found from this observation.…”

Development of highly efficient and potential material for toxic p-nitrophenol is an important design for sensitive detection of hazardous species from ecology and environment. Here it is developed, an efficient as well as selective of p-nitrophenol using binary material by electrochemical performances, including good linearity, lower detection limit, good stability, higher reproducibility and extreme sensitivity. The prepared electrode was fabricated by immobilization of SnO2/CdO microcubes (MCs) with conducting coating binders by using well-known glassy carbon electrode (GCE). The proposed MCs with SnO2/CdO were well-functionalized and prepared by facile hydrothermal technique. The general instrumentation namely, FTIR, UV/vis, FESEM, XPS, TEM, EDS, and powder XRD were employed for the morphological evaluation of the prepared doped MCs, structural, optical and elemental analyses. The large dynamic range (LDR) from 1.0 to 0.01 mM with 0.13 pM detection limit (S/N = 3), limit of quantification (LOQ; 0.43 pM), and an excellent sensitivity of 7.12 µAµM−1cm−2 were exhibited by the fabricated binary material based on SnO2/CdO MCs for selective p-nitrophenol capturing. In shortly, the SnO2/CdO MCs can be employed as an efficient electron mediator with binary materials fabricated GCE for capturing the p-nitrophenol at ultra-trace amounts. Then the binary synthesized material of SnO2/CdO MCs is used as potential and sensitive sensor layer by stable electrochemical approach for sensitive capturing of toxic p-nitrophenol from environmental samples.
