Eu was successfully incorporated into Sb2S3 thin films for proficient photocatalytic degradation of rhodamine B (RhB) dye under visible light. In this work, we reported the effect incorporating ions at different doping levels to tailor their structural, optical, electrical, and properties. Grazing incidence X-ray diffraction (GIXRD) analysis revealed that fabricated exhibited an orthorhombic crystalline structure. Additionally, GIXRD peaks shifted towards lower angles as level increased. The Williamson-Hall method used estimate effective crystallite size considering strain components. field emission scanning electron microscope (FESEM) characterisation demonstrated grain decreased a denser microstructure observed degree estimated optical band gap (E g) value increases from 1.67 eV 1.72 rises 0 8 at%, making suitable applications. activities pristine Eu-doped were evaluated by highly toxic Rhodamine dark various light conditions 120 min. A remarkable photodegradation rate achieved with optimal 4 at% Eu, demonstrating 90.99% RhB. Electrochemical impedance spectroscopy (EIS) measurements show lifespan photoinduced electrons Eu3+ samples is approximately 10 fold higher than sample. terms chemical kinetics, RhB Sb2S3:Eu (4 Eu) photocatalyst found follow pseudo-first-order kinetics constant 0.049 min-1 irradiation. conceivable molecular mechanism photocatalysts also provided. These results highlight potential advanced Specifically, exhibits favourable Thus, it concluded these are remediation dye-contaminated wastewater.
