LIGHT EMITTING DEVICE AND PHOSPHOR FOR THE SAME

摘要

Provided is a light emitting device including a light emititng chip, and a phosphor through which a light emitting from the light emitting chip at least partially passes such that the light is converted into lights having at least two different wavelengths and emitted. The phosphor includes a silicate phosphor having a chemical formula of Sr3-xSiO5:Eu<2+> x(0 < x < 1) to excite a second light having a first centered emission peak using the first light and a sulfide phosphor having a chemical formula of Srl-xGa2S4:Eu<2+> x(0.001 < x < 1) to excite a third light having a second centered emission peak using the first light.
