Abstract

Glare proof glass is a functional glass material which absorbs ultraviolet and blue light being harmful to the human eyes while maintaining a high overall transmittance. In this paper, silicate glasses with different amounts of Ce 3+ Sm 3+ and Ho 3+ were prepared by high temperature melting method, and their expansion coefficient, refractive index, density and tr ansmission spectrum were measured. The results showed that when the doping concentration of three rare earth ions Ce 3+ Sm 3+ and Ho 3+ in silicate matrix is 1.5 wt%, 31.1 wt% and 2.3 wt% the glass samples have a large absorption in ultraviolet and blue lig ht regions, and the glare can be prevented..

Keywords
