摘 要：Eu3+ doped TiO2 anatase spheres were obtained by modified sol-gel approach.Spheres（110—250 nm） are composed of smaller（5-15 nm） nanocrystals and exhibit red emission under UV light excitation.Materials were synthesized by multi-step method from glycolated titania alkoxides.Europium doped（1.0 mol%） and non-doped spheres were synthesized.Their optical and structural properties were compared by materials characterization methods,such as X-ray powder diffraction,transmission electron microscopy and PL spectroscopy.Doped TiO2 spheres are crystalline phase pure and exhibit high luminescence intensity.
