Problems solved by technology

At present, there are more than 300 kinds of optical glasses made of rare earth oxides in the world. It is known that the rare earth ions used for doping include common elements such as Er3+, Ho3+, Tm3+, Yb3+, etc., but there are no research results or the market. At the same time, rare earth-doped glass with effective absorption and anti-glare for 300nm-400nm ultraviolet light band, 490nm-525nm blue-green light band and 560nm-605nm yellow light band appeared

Abstract

The invention discloses rare earth doped glass and a preparation method thereof. The rare earth doped glass comprises the following components in percentage by mole: 45-70% of a glass network structure forming body, 6-20% of a weather-resistant stabilizer, 8-20% of a softening stabilizer, 0-15% of a cosolvent, 0-5% of a glass stabilizer, 0-2% of a defoaming agent and 0.5-5% of a specific light band absorbent. The rare earth doped glass prepared by the formula has the effects of isolating ultraviolet rays, preventing dazzle, protecting eyes, improving comfort of human eyes, and improving colorsaturation and definition of images.

Description

technical field [0001] The invention relates to the technical field of glass manufacturing, in particular to a rare earth-doped glass and a preparation method thereof. Background technique [0002] Rare earth doped glass is a special glass containing one or more rare earth ions, which can be used as spectacle lenses, LED lampshades, camera lenses, medical endoscopes, camera filters, etc. The ability of rare earth-doped glass to absorb light in different spectral ranges determines its performance. [0003] The solar spectrum includes several spectral ranges such as radio waves, infrared rays, visible light, ultraviolet rays, X-rays, and gamma rays. Among them, the wavelength in the range of 400nm to 760nm is visible light, which is divided into seven colors of red, orange, yellow, green, blue, blue and purple after being scattered, and it is white light when gathered together. Infrared light has a wavelength greater than 760nm, and ultraviolet light has a wavelength less th...
