Sol-gel method was used to prepare SiO2 film, and it was tested by semiconductor laser and UV spectrophotometer. On this basis, different concentrations of Eu3+ ions were added to prepare doped SiO2 films. The films were characterized by scanning electron microscope and Fourier transform infrared spectrometer, and the effect of adding Eu3+ on the structure and optical properties of the films was analyzed. The results show that the transmittance of the film reaches more than 98% and the reflectivity is less than 1% when 15% Eu3+ is doped, and the film has excellent optical properties and can be used as a material for optical devices.Keywords: SiO2; Eu3+; anti-reflection thin film; preparation; optical properties
