PHOSPHOR AND LIGHT EMITTING DEVICE HAVING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a phosphor and a light emitting device including the same.SOLUTION: The light emitting device includes a light emitting chip, a phosphor layer on the light emitting chip, and a phosphor added onto the phosphor layer to absorb light emitted from the light emitting chip and emit a central wavelength having a first blue color. The phosphor has a composition formula of LaOSiAlN:Ce, where the range of x is 2≤x≤8 and the range of y includes 3≤y≤12.
