Latest Patents

Ozawa holds a patent for a "Method of manufacturing phosphor powder, phosphor powder, and phosphor composition." This patent describes a process for creating highly crystallized phosphor powder. The method involves making a raw material solution containing metal and/or semimetal elements into fine liquid droplets. These droplets are then subjected to decomposition by heating at temperatures ranging from 500 to 1800°C to produce hollow or porous precursor particles. The precursor particles are subsequently heated to crystallize them while maintaining their hollow or porous form. Finally, the crystallized particles are ground to a predetermined particle size. The resulting phosphor powder exhibits high luminance, excellent crystallinity, and superior light emission characteristics.
