Advanced near-infrared-driven photocatalyst: Fabrication, characterization, and photocatalytic performance of β-NaYF4:Yb3+,Tm3+@TiO2 core@shell microcrystals

The β-NaYF4:Yb3+,Tm3+@TiO2 core@shell photocatalyst consisted of uniform hexagonal phase NaYF4 microcrystals rods and anatase TiO2 shells was fabricated and the composite has been shown to be an advanced near-infrared-driven photocatalyst as evaluated by the discoloration of Methylene Blue, Methyl Orange and Rhodamine B under the irradiation of 980 nm laser.
