Copper barium iron sulphide (CBFS) thin films were synthesized using a chemical bath deposition (CBD) method on glass substrates for 10 hours. The study used solutions of copper (II) chloride dehydrate, barium chloride, iron (II) chloride, and thiourea as the sources of the elements (copper, barium, iron and sulphur) to fabricate films of thickness 105.81 nm at a pH of 9.60. Fourier Transform Infrared (FTIR) Spectroscopy was employed to analyze the chemical characteristics of the aqueous precursor and the deposited films at 30 ℃. Experimental observations revealed distinctive CBFS absorption bands below 900 in the FTIR spectrum of the precursor. The optical band gap energy was determined to be , with the absorbance decreasing (from 0.6 to 0.3 au) as the wavelength increased from 300 to 1000 nm. The optical constants of extinction coefficient and optical conductivity were found to be 0.05 and 0.7 respectively at 3.50 eV. Scanning electron microscopy (SEM) micrographs showed that the films were crack-free, rough, and uniformly covered with grains of various shapes. Electron dispersive x-ray (EDX) revealed that the deposited material consists of copper, barium, iron and sulphur. X-ray diffraction (XRD) analysis confirmed the crystalline structure of the deposited films. Hence, the crystalline sizes (D), dislocation density (δ), and the strain function (ε) were also evaluated to range from 29.91 to 135.53 nm, and 0.00079 to 0.00473, respectively. These findings suggest that the synthesized CBFS thin films have potential for integration in diverse electronic applications.
