Phosphor and light emitting device package including the same

摘要

Embodiments provide a phosphor including a silicate-based first phosphor emitting light having a yellow wavelength, a nitride-based second phosphor emitting light having a green wavelength, and a nitride-based third phosphor emitting light having a red wavelength. A full width at half maximum of the spectrum of mixed light emitted from the first phosphor to the third phosphor as the phosphors are excited by light having a blue wavelength is 110 nm or more.

1. A light emitting device package comprising:
a first electrode and a second electrode electrically isolated from each other; at least one light emitting device electrically connected to each of the first electrode and the second electrode to emit light having a first wavelength; and phosphors excited by light having a blue wavelength emitted from the light emitting device to emit light having a second wavelength, the phosphors including a silicate-based first phosphor emitting light having a yellow wavelength, a nitride-based second phosphor emitting light having a green wavelength, and a nitride-based third phosphor emitting light having a red wavelength, wherein a full width at half maximum of the spectrum of mixed light, emitted from the first phosphor to the third phosphor as the phosphors are excited by light having a blue wavelength, is 110 nm or more.
