摘要:
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.
