AI Technical Summary
Existing green phosphors have low luminous efficiency and wide half-width, which cannot meet the requirements of ultra-high color gamut displays.
The luminescent material, composed of inorganic compound Al-aDdE2+eG2-gMmXx, elements A, D, E, G, M, and X, was formed by adjusting the element types and doping ratios to form a crystal structure identical to SrAl2Si2O8. This optimized the crystal structure and improved the doping concentration of Mn2+ and the luminescence efficiency.
It significantly improves luminous intensity and external quantum efficiency, enhances the color gamut of the light-emitting device, and meets the application requirements of ultra-high color gamut LCD backlights.
