Cuprous oxide thin films with different weights were prepared on glass substrates by the CBD method. The results show that the weight significantly affects the structural, morphological, and optical properties of the thin films.
Cuprous oxide (Cu2O) thin films were prepared for the different weights (0.08, 0.09, 0.10, 0.13, and 0.14 g) on glass substrates by the chemical bath deposition (CBD) method. The effects of weight on the structural, morphological, and optical properties of thin films were investigated. The XRD pattern shows cubic structured Cu2O thin films and the crystallinity is increased with an increase in weight. The average crystallite size is also increased from 10 to 17 nm. The FESEM images picturized cubic and irregular-shaped non-homogeneous particles. The transmittance is found to be decreased with an increase in weight. The direct energy bandgap decreased from 2.26 eV to 2.17 eV as the weight increased. Also, the extinction coefficient, refractive index, and dielectric coefficients have been affected by the variation of weight.
