dc.description.abstractIn this study, green-emitting Na(2)CaPO(4)F:Eu(2+) phosphors were synthesized by solid-state reactions. The excitation spectra of the phosphors showed a broad hump between 250 and 450 nm; the spectra match well with the near-ultraviolet (NUV) emission spectra of light-emitting diodes (LEDs). The emission spectrum showed an intense broad emission band centered at 506 nm. White LEDs were fabricated by integrating a 390 nm NUV chip comprising blue-emitting BaMgAl(10)O(17):Eu(2+), green-emitting Na(2)CaPO(4)F:0.02 Eu(2+), and red-emitting CaAlSiN(3):Eu(2+) phosphors into a single package; the white LEDs exhibited white light with a correlated color temperature of 5540 K. a color-rendering index of 90.75, and color coordinates (0.332, 0.365) close to those of ideal white light.
