Problems solved by technology

[0003] The miniaturization and light weight of optoelectronic terminal products promote the thinner and thinner near-infrared light-absorbing glass, but if the glass is directly thinned, the near-infrared light absorption performance of the glass will also become smaller, and the required spectral characteristics cannot be obtained, so often It is necessary to increase the coloring component Cu 2+ content to make up for the reduction in...

Abstract

The invention provides glass. The components of the glass comprise, in percent by weight: 55-75% of P2O5, 2-15% of Al2O3, 5-20% of CuO, 1-25% of Rn2O, 0-25% of RO, and 0.02-3% of V2O5, wherein Li2O/Rn2O is 0.3-1.0, the Rn2O is a total content of Li2O, Na2O and K2O, and the RO is a total content of MgO, CaO, SrO and BaO. By a reasonable component design, the obtained glass has excellent devitrification resistance in the case of having a high Cu content. At the same time, the glass is suitable for chemical strengthening, and a glass product obtained after chemical strengthening has excellent bending strength.

Description

technical field [0001] The invention relates to a glass, in particular to a near-infrared light absorbing glass and a glass product. Background technique [0002] In recent years, the spectral sensitivity of semiconductor imaging elements such as CCD and CMOS used in digital cameras, camera phones, and VTR cameras has spread from the visible range to the near-infrared range around 1100nm, and filters that absorb light in the near-infrared range have been used. The device can obtain a degree of visual acuity similar to that of a human being. Therefore, the demand for filters for color sensitivity correction is increasing, which puts forward higher requirements for near-infrared light-absorbing functional glass used to manufacture such filters; and, since near-infrared light-absorbing glass is used in Applications in fields such as smartphones also put forward higher requirements on the performance of glass such as bending strength. [0003] The miniaturization and light wei...
