Response to Comment on 'Intimate Coupling of Photocatalysis and Biodegradation for Degrading Phenol Using Different Light Types: Visible Light vs UV Light'

摘要

We thank Cates (2015) for his comments on our paper. In his comment, Cates (1) believes that Er~(3+):YAlO_3 is not capable of emitting significant amounts of UV via upconversion and the UV may be "artefactual"; (2) suspects that the LED light source may include emissions tailing into the UV range. Accordingly, we provide more detailed results regarding fluorescence spectrum, light source spectrum and photocatalytic activity of Er~(3+):YAlO_3/TiO_2 at the following two aspects to debate Cates's query.
