Primary Model

In this work, an upconversion luminescence agent, crystallized Er3 + :YAlO3, was synthesized and then coated by the nano-sized TiO2 film through sol–gel technique. A novel TiO2 photocatalyst, Er3 + :YAlO3/TiO2, with high activity in visible light was subsequently prepared. The Er3 + :YAlO3 and Er3 + :YAlO3/TiO2 were characterized by X-ray diffraction (XRD) and transmission electron microscope (TEM). The photocatalytic activity of Er3 + :YAlO3/TiO2 photocatalyst was tested by the degradation of acid red B in aqueous solution as the primary model compound under visible light irradiation. The experimental results proved that the prepared TiO2-coated crystallized Er3 + :YAlO3 was able to decompose the acid red B efficiently, and it is promising to use the idea to develop new TiO2 photocatalyst with high activity for photocatalytic degradation under visible light.
