Kaalumines
Kaalumines is a synthetic luminescent ceramic material used as a phosphor in lighting and display technologies. It belongs to the family of potassium-aluminosilicate phosphors and is doped with rare-earth ions to enable photoluminescence when excited by ultraviolet or blue light.
Composition and structure: The material consists of a potassium aluminum silicate host lattice, with dopants such
Properties: Kaalumines exhibits bright, broad-band emission in the visible range, high quantum efficiency, and good thermal
Synthesis and processing: The material is produced by solid-state reaction or sol-gel methods, followed by high-temperature
Applications and outlook: The primary application is as a phosphor in white LEDs and backlit displays, where
