Photocatalysts based on semiconducting chalcogenides due to their adaptable physio-chemical characteristics are attracting attention. In this work, Bi-doped PbS (henceforth PbS:Bi) was prepared using a straightforward chemical precipitation approach, and the influence of γ-irradiation on PbS's photocatalytic ability was investigated. Synthesized samples were confirmed structurally and chemically.

- * Characterization methods like X-ray diffraction and electron microscopy revealed that gamma-irradiation increased the optical bandgap of PbS from 1.95 eV to 2.45 eV.
- * The gamma-irradiated PbCuSrS sample showed significant photocatalytic performance, achieving 74.02% degradation of methylene blue dye in 160 minutes, along with 69.4% stability after three usage cycles.
