Impact of Bi and its oxide phases on Bi<sub>2</sub>S<sub>3</sub> compound transformation and photoelectrochemical performance
Bi<sub>2</sub>S<sub>3</sub> films were synthesized by sulfurizing sputtered Bi and Bi<sub>2</sub>O<sub>3</sub> (α, β phases). Metallic Bi enabled a more efficient conversion, while Bi<sub>2</sub>O<sub>3</sub> impeded Bi<sub>2</sub>S<sub>3</sub> formation due to its strong Bi-O bonds. Sulfur distribution along film depth significantly affected photoelectrochemical (PEC) performance, underscoring the critical importance of precursor selection for optimized functionality.
