The ZrO2∶Eu 3+, Y 3+ (Eu-YSZ) light conversion films are prepared on the fused silica substrates by using the chemical solution deposition method. The effects of Eu 3+and Y 3+ doping concentrations on crystal structure, surface morphology and optical properties of thin films are investigated. Under the irradiation of ultraviolet light with a wavelength of 396 nm and blue light with a wavelength of 466 nm, the Eu-YSZ thin films show bright red emission bands centered at 593 nm and 609 nm, which are attributed to the energy level transitions of Eu 3+ ions. In addition, the thin films show a relatively high visible light transmittance. The study suggests that the Eu-YSZ light conversion films are beneficial to reduce the damage of short wave blue light to the retina of human eyes.
