摘要： According to an embodiment, a phosphor composition and a light-emitting device package including the same includes a first phosphor excited by an excited light source so as to emit light of a first wavelength area; a second phosphor excited by the excited light source so as to emit light of a second wavelength area; and a third phosphor excited by the excited light source so as to emit light of a third wavelength area. Therefore, light emitted from the phosphor composition has an improved color rendering index due to an increase in the intensity of light in a cyan wavelength area, and has an improved light velocity due to a shortened wavelength of light in a red wavelength area.

摘要： The present invention provides a red-light emitting phosphor that exhibits high luminous efficacy and emits light when excited by light having an emission peak in the blue region; and a method for manufacturing said phosphor. The phosphor represented by general formula (A): a(Si1-x-y,Tix,Mny)Fb and also characterized in that the half-band width of a diffraction pattern attributed to the (400) plane is not less than 0.2° determined by X-ray powder diffractometry. This phosphor can be manufactured by preparing a reaction solution consisting of an aqueous solution containing potassium permanganate and hydrogen fluoride, immersing a silicon source in said reaction solution, and reacting them for 20 to 80 minutes.
