Herein, a full-spectrum-response Bi₃O₄Br:Er³⁺@Bi₂O_3- _x core-shell S-scheme heterojunction is designed with [Bi─O] tetrahedral sharing using upconversion (UC) functionality, photothermal effects, and interfacial engineering. The UC function of Er³⁺ and plasmon resonance effect of Bi₂O_3- _x greatly improves the utilization of sunlight.
