Fabrication of Er³⁺/Yb³⁺ Co-Doped Bi₅O₇I Microsphere With Upconversion Luminescence and Enhanced Photocatalytic Activity for Bisphenol A Degradation.

ABSTRACT: Er³⁺/Yb³⁺ co-doped Bi₅O₇I uniform porous microsphere photocatalysts were synthesized by a two-step chemical method, which possesses excellent photocatalytic performance and upconversion luminescence property. The photocatalytic performance of the photocatalysts was studied by degradation of bisphenol A in aqueous solution under visible light and different monochromatic light irradiation. The photocatalytic performance of Er³⁺/Yb³⁺ co-doped Bi₅O₇I sample is better than that of the pristine Bi₅O₇I and Er³⁺-doped Bi₅O₇I samples. Moreover, Er³⁺/Yb³⁺ co-doped Bi₅O₇I possesses photocatalytic ability with a red l
