By using the chemical bath approach, CuS, and Al-doped CuS thin films were formed onto
glass substrates. To enhance the photocatalytic capabilities of the traditional CdS thin film,
Al 3+ ions were used as doping element. Investigations were done into how the amount of Al
doping affected the physical characteristics of CuS films by varying Al content as 2 wt%, 4
wt%, 6 wt%, and 8 wt%). The bandgap energy, thickness, morphology, and crystalline
structure of CuS and Al-doped CuS thin films were examined. By using FTIR and FT-Raman …
