Preparation And Performance Characterization Of Anti-Glare Glass

Glare refers to a visual condition which the light into the human eye scattering,reducing the field of view contrast.Glare of the production will not only bring inconvenience to our lives,but also bring health and safety hazards,so the public attention for the glare is getting higher and higher.In our everyday exposure to light,ultraviolet and blue light because of its short wavelength,high energy,will not only lead to glare,but also harm the human eye.Glass materials in the display,lights and LED light source widely used,therefore,this paper mainly in the glass material to achieve the absorption of ultraviolet and blue light in order to achieve the purpose of anti-glare.In this paper,silicate glass samples with different contents of Ce³⁺,Sm³⁺,Ho³⁺ were prepared by high temperature melting method.The thermal expansion coefficient,XRD,refractive index,density and transmission spectra were measured.Through the analysis of the mechanical properties and optical properties of each sample,the cutoff wavelength of the sample is about 360 nm when the Ce³⁺ content is 0.5mol%.When the Sm³⁺ doping concentration is 1.5mol%,the transmittance at 400 nm is 4.2% and the transmittance at 470 nm is 48.9%.When the content of Ho³⁺ is 0.4 mol%,the large absorption of shortwave blue light while ensuring high transmittance of visible light.
