Abstract: PbCuSO4 thin films were prepared by SILAR method on glass substrates using Pb(NO3)2 and CuSO4:5H2O as the cationic precursors, hydrogen peroxide and thiourea as the anionic precursors and Triethanolamine (TEA) (C6H15NO3) as the complexing agent. The samples were subjected to heat treatments at 100oC , 150oC, 200oC, and 250oC for 1hour. The samples were transparent and adherent to the substrates. The transmittance increases from 0.13 to 0.64 as the wavelength increases from 300nm to 1100nm for the samples as measured by UV 1800 series double beam spectrophotometer. The band gaps obtained under various thermal treatments are between 3.5 ±0.05eV to 3.75±0.05eV. The thickness for PC1 is 386nm, PC2 is 592nm, PC3 is 403.29nm and PC4 is 399nm. These properties of the material makes it suitable for applications in solar cells, gas sensor, thin absorber, aesthetic window, smart window antireflection coating.
