In order to utilize visible light more effectively, a novel Er ³⁺:Y₃Al₅O₁₂/Bi₂WO ₆ photocatalyst was designed, in which Er³⁺:Y ₃Al₅O₁₂ is a kind of upconversion luminescence agent and can emit ultraviolet light under visible light excitation. The photo-degradation of a typical model pollutant, phenol, demonstrated that Er³⁺:Y₃Al₅O₁₂/Bi₂WO ₆ photocatalyst exhibited much enhanced photo-activity than bare Bi₂WO₆ under simulated solar light irradiation. Moreover, the Er³⁺:Y₃Al₅O₁₂/Bi ₂WO₆ photocatalyst also showed photo-activity under visible light with wavelengths beyond the absorption edge of Bi ₂WO₆, further testifying the upconversion effect of Er³⁺:Y₃Al₅O₁₂.
