Abstract

A method for manufacturing integral chromatic luminous vycor glass, which is characterized in that the method comprises: (1) preparing cellular glass, (2) preparing rare earth with certain concentration or transition metal luminous solion, (3) introducing the rare earth or transition metal luminous solion in the cellular glass by employing the segmental doping method, (4) drying the cellular glassdoped with the rare earth or transition metal luminous solion in the air at a temperature of 200-800DEG C and (5)placing the dried cellular glass doped with the luminous solion in a high temperaturefurnace and eliminating micropores to form dense, transparent and integral chromatic luminous vycor glass via solid-phase sintering of air at a temperature of 1100-1250DEG C or reducing atmosphere. The glass of the invention is colorless in appearance, dense and transparent, and can emit light with a plurality of colors when being shined by ultraviolet lamp. The method is simple in manufacturing process, needless in binding agent and low in cost, and has perfect optical property, chemical stability and mechanical strength, which are similar to that of quartz glass.

Description

technical field [0001] The invention relates to colored luminous glass, in particular to a method for manufacturing integrated colored luminous high-silica glass. Background technique [0002] Glass is an excellent application material with a series of very valuable properties: transparency, hardness, good chemical stability and optical properties. Compared with crystals and phosphors, glass is easier to be processed into products of various sizes and shapes, and the price is low, and the production cost is low. Visible luminescence of various wavelengths can be obtained by doping appropriate rare earth or transition metal ions in glass, which is widely used in multi-color display, visible laser, colored lamps, advertising lighting and other fields. However, in traditional manufacturing methods, colored luminous glass mostly achieves multiple colors through the combination of multiple pieces of monochromatic luminous glass. Usually in the manufacturing process, a variety o...
