Abstract
The invention belongs to the technical field of optical glass preparation, and discloses an infrared germanium antimonate glass and a preparation method thereof. The glass is made of GeO 2 -Sb 2 o 3 It is prepared by adding various other oxides on the basis of it. It has a wide infrared transmission range, high refractive index, low phonon energy, good anti-crystallization ability, thermal stability, and mechanical properties. It is suitable for use as a mid-infrared window material.
Description
technical field [0001] The invention relates to the technical field of optical glass preparation, and provides an infrared germanium antimonate glass and a preparation method. Background technique [0002] Infrared materials are widely used in the fields of military, environmental monitoring, medical treatment, optical fiber communication and basic research. Commonly used infrared crystal materials include ZnS, ZnXe, sapphire, magnesium fluoride, calcium fluoride, etc., which are mainly used in optical lens window materials. This type of material has high infrared transmittance, but has low hardness, difficult manufacturing and processing, Disadvantages such as high cost, and it is difficult to apply to fiber lasers. The second is mainly glass materials, which are also the main source of infrared optical fiber materials at present, including germanate glass, fluoride glass, quartz glass and tellurite glass, etc., but fluoride glass has poor chemical stability, difficult pre...
