    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.
