Problems solved by technology

[0003] The miniaturization and light weight of optoelectronic terminal products promote the thinner and thinner near-infrared light absorption 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

Abstract

The invention provides glass. The glass comprises the following components, in percentages by mole: 38-65% of P2O5, 2-15% of Al2O3, 8-25% of CuO, 5-40% of Rn2O, 1-30% of RO, and 0-3% of V2O5, wherein a ratio of the Li2O to the Rn2O is 0.4 to 1.0, a ratio of (the Li2O+the CuO) to the P2O5 is 0.3 to 1.2, a content of the Rn2O is a total content of Li2O, Na2O and K2O, and a content of the RO is a total content of MgO, CaO, SrO and BaO. According to the glass provided by the invention, through reasonable component design, the glass obtained by the invention has excellent anti-crystallization property in the case of having a high Cu content; and at the same time, the glass is suitable for chemical strengthening, and a glass product obtained by 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, a glass product and a manufacturing method thereof. 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 glasses used to manufacture such filters, that is, such glasses are required to have Moreover, due to the application of near-infrared light-absorbing glass in smartphones and other fields, higher requirements are placed on the performance of ...
