“…The real and imaginary parts of the dielectric constant at λ = 550 nm are found as 6.35 and 0.77, respectively. These values are consistent with reported data [14,18] involving PbS films grown by CBD.…”

Lead sulfide thin films are deposited on glass substrates at room temperature for 2 h by chemical bath deposition. The structure, surface morphology, optical and electrical properties of the thin films are characterized by X-ray diffraction, scanning electron microscopy, atomic force microscopy, optical absorption spectroscopy and the Hall effect measurements. The obtained films show the formation of well crystallized PbS with a cubic rock salt structure and with the preferential orientation (111) plane. The lattice parameter and crystallite size of the films are found as a = 600 Å and 62 nm from the X-ray reflectivity data from the atomic force microscopy image, respectively. The band gap width of the films is determined as 2.84 eV. The optical parameters of the films such as refractive index, extinction coefficient, real and imaginary parts of dielectric constant are evaluated. Moreover, from the Hall measurements, electrical resistivity, conductivity carrier mobility, and carrier concentration of the films are determined as 3.722 Ω m, 0.

“…The sharp absorption edges occurred at wavelength less than 530nm and the absorption edge of the film slightly shift towards longer wavelength with increasing annealing temperature. The highest absorbance values are observed from the annealed samples with the critical annealed temperature for optimum absorbance at 140 o C. Similar behaviour was noted by Elmas et al and Abbas et al [11,12]. C is displayed in Fig.…”
