Abstract: Disclosed are phosphors and, more particularly, yellow light emitting phosphors and light emitting device packages using the same. The yellow light emitting phosphor includes a first phosphor including at least one of Lu3Al5O12:Ce, SrSi2O2N2, and β-type SiAlON and a second phosphor mixed with the first phosphor to form a mixture, the second phosphor including α-type SiAlON(Li-α-SiAlON) containing Li as a metal component, wherein the second phosphor emits light having a central wavelength in a range of 550 nm to 590 nm by being excited by near ultraviolet (UV) or blue light, The mixture of the first phosphor and the second phosphor is excited by the near UV or blue light to emit yellow light.

Abstract: Disclosed are phosphors and, more particularly, yellow light emitting phosphors and light emitting device packages using the same. The yellow light emitting phosphor includes a first phosphor to emit light having a central wavelength located within a band of 510 nm to 550 nm, a second phosphor adapted to be mixed with the first phosphor to emit light having a central wavelength located within a band of 560 nm to 600 nm, and a third phosphor adapted to be mixed with the first and second phosphors to emit light having a central wavelength located within a band of 610 nm to 630 nm, the third phosphor having a light absorption rate of 50% or less at a wavelength of 550 nm.
