Abstract

Exploring novel visible light responsive photocatalysts is one of greatly significant issues from the viewpoint of using solar energy. Here we report the yellow-orange emitting α-Si ₃ N ₄ -doped Lu ₃ Al ₅ O ₁₂ :Ce ³⁺ (Lu ₃ Al _5-x Si _x O _12-x N _x :Ce ³⁺ ) phosphors as a noble-metal-free co-catalyst for enhanced visible light photocatalytic activity of ZnO. The results show that ZnO-Lu ₃ Al _5-x Si _x O _12-x N _x :Ce ³⁺ hybrid photocatalysts using a fast microwave-assisted approach exhibits a 91% methylene blue (MB) degradation under visible light irradiation at 240 min, which evidence the synergistic effect of ZnO and Lu ₃ Al _5-x Si _x O _12-x N _x :Ce ³⁺ that suppress the rate of charge recombination and increase the self-sensitized degradation of MB. ZnO-down conversion phosphors can be envisaged as potential candidate in environmental engineering and solar energy applications.
