Borate chloride-based phosphor, and light-emitting diode, fluorescent lamp and plasma display panel including the same

Abstract

Provided are a borate chloride phosphor represented by Formula 1 below, a light-emitting diode (LED) including the same, a lamp, a self-emissive liquid crystal display device (LCD), and a plasma display device (PDP). (Ca(1−x−a−b−c)BaaSrbMgcEux)2B6O10.5Cl,Formula 1 where 0<x≦0.2, 0≦a≦0.5, 0≦b≦0.95, 0≦c≦0.5. The borate chloride phosphor has good chemical properties and is thermally stable and easy to manufacture. The borate chloride phosphor exhibits high brightness due to a UV excitation light source in a wavelength of 280-410 nm, and emits blue light in a wavelength range of 425-455 nm. Accordingly, the borate chloride phosphor of the present invention can be applied to an LED, a lamp, a PDP, or a self-emissive LCD.
