1. Luminous ceramic glaze is composed of nano-magnesia as an important component of low-temperature glaze and other components such as silicon oxide, aluminum oxide, calcium carbonate, etc., add water to paste and paint on the surface of ceramic products, and then sinter at a high temperature of about 800 ° C. be made of.
It has the following characteristics: long afterglow time, up to 10 hours, under the excitation of ultraviolet and visible light, it emits blue-green light and green light, and has heat release and luminescence in the temperature range of 40 ℃
2. High-brightness hydrolysis-resistant rare-earth-activated luminescent materials are made of nano-magnesia, alumina, boron oxide and rare-earth oxides through high-temperature solid-state reaction.
Colors are light yellow, light blue and purple. The material can be widely used in coatings, plastics, ceramics, enamel, decoration and other industries.
3. Rare earth long afterglow luminescent material is a luminescent material prepared by mixing and sintering nano-magnesia, alumina, silicon dioxide, mineralizer, rare earth activator, etc. according to the proportion, and has high brightness and long afterglow. Good water resistance, no radioactivity, no harm to the environment and so on.
4. Artificial luminous gemstones are made by using commercially available luminescent micropowder and introducing nano-magnesium oxide as a reinforcing agent. After regular warm isostatic pressing, they are sintered at high temperature in an electric furnace with a reducing atmosphere.
The prepared luminous gem has a hardness of 6.5-7 degrees, a relative density of 3.3-3.8, and has long-lasting phosphorescence characteristics. The problem of low utilization rate of the luminescent micropowder is solved, and for the process of synthesizing luminous gemstones, the synthesis temperature and synthesis time are also reduced, thereby reducing the production cost.
5. Phosphor for Led displays, especially for phosphors for electroluminescent displays, is a new type of laminated product to improve the fluorescence based on thioaluminate for AC thick film dielectric electroluminescent displays Material stability. The novel structure includes a rare earth-activated alkaline earth thioaluminate phosphor film layer and a nano-magnesia layer or a layer containing nano-magnesia directly adjacent to and in contact with the bottom of the phosphor film layer.
