The application of nano magnesium oxide in luminescent materials is mainly reflected in the following aspects:
Luminous ceramic glaze: nanometer magnesium oxide as an important component of low-temperature glaze, mixed with silicon oxide, alumina, calcium carbonate and other components, sintered at high temperature to produce luminous ceramic glaze. This glaze has a long afterglow time, light-emitting colors and other characteristics, widely used in ceramic products on the surface.
Rare earth activated luminescent materials: nanometer magnesium oxide and alumina, boron oxide and rare earth oxides and other components after high temperature solid state should be produced high brightness, long afterglow of rare earth activated luminescent materials. This material has high initial brightness and long afterglow time, which is suitable for coating, plastics, ceramics, enamel and other industries.
Artificial luminous gemstones: nano-magnesium oxide is used as an enhancer for the synthesis of luminous gemstones. The artificial luminous gemstone made by high temperature sintering has long afterglow phosphorescence characteristics, high hardness, high relative density, and is widely used in decorations and collections.
LED display phosphor: In LED displays, magnesium oxide nanolayers or layers containing magnesium oxide nanolayers are used in electroluminescent displays to improve the operational stability of the fluorescent material. This structure is suitable for AC thick film dielectric electroluminescent displays with excellent luminescence performance.
Specific mechanisms of action of magnesium oxide nanoparticles in luminescent materials include:
Improve the luminescence efficiency and stability of the material: the high specific surface area and pore structure of nano-magnesium oxide are favorable for the rapid transport of charge, thus improving the luminescence efficiency and stability of the material.
Enhance the hydrolysis resistance of the material: by combining with other components, nano-magnesium oxide can significantly improve the hydrolysis resistance of the material and extend its service life.
Improve the physical properties of the material: the addition of nano-magnesium oxide can improve the hardness, density and other physical properties of the material, so that it is more suitable for application in a variety of decorative and functional materials.
In summary, the application of nano-magnesium oxide in luminescent materials not only improves the luminescence efficiency and stability of the material, but also extends its application in the field of decoration and lighting.
