Abstract

The invention relates to fluorescent powder / silicon-based mesoporous material composite fluorescent glass and a preparation method thereof. The fluorescent glass comprises the following raw materials in percentage by mol: 95-99.9% of silicon-based mesoporous material and 0.1-5% of fluorescent powder. The preparation method comprises the following steps: (1) weighing the raw materials, performing ball milling, mixing, and drying for later use; and (2) filling the powder after ball milling and drying into a graphite mold, placing in the chamber of a discharge plasma sintering furnace, sintering in vacuum, an inert atmosphere or a reducing atmosphere, then performing furnace cooling to room temperature, sanding, and polishing. In addition to the advantages of glass for the existing white light LED (light-emitting diode), the invention further ensures that the stability is more excellent in comparison with glass additionally containing alkali metal oxide, alkaline-earth metal oxide or other network modifier due to quartz glass used as the substrate material; and the preparation process is simple and low in cost, and has favorable application prospects.

Description

technical field

[0001] The invention belongs to the field of luminescent glass and its preparation, and in particular relates to a luminescent glass made of fluorescent powder composite silicon-based mesoporous material and a preparation method thereof. Background technique

[0002] The application of white light LED (light emitting diode) in the field of lighting is an inevitable trend of technological development. In the 1990s, the application field of LED expanded from the traditional application field such as indicator light and signal light to the field of display screen and white light lighting. As the global energy shortage becomes more and more serious, energy conservation and environmental protection become the theme of the world. White LEDs have attracted great attention from various countries due to their long service life, high efficiency, energy saving, and environmental protection. Japan, the United States, South Korea, and China have all issued national Level...
