Claims15
A red phosphor comprising a coating layer formed on a surface, and
- the red phosphor satisfies a following structural fog formula:
- K2M1-xMn4+XF6 [Structural Formula]
- wherein M is at least oils element selected from the group consisting of a Group IV element and a Group XIV element, and the X satisfies 0.028≤X≤0.055.
A light emitting device comprising:
- a light emitting device (LED) configured to emit first light;
- and
- a wavelength conversion layer configured to convert a wavelength of the first light,
- wherein the wavelength conversion layer comprises:
- a first phosphor configured to absorb the first light to emit light in a green wavelength range;
- and
- a second phosphor configured to absorb the first light to emit light in a red wavelength range,
- wherein the second phosphor satisfies a following structural formula:
- K2M1-xMn4+XF6 [Structural Formula]
- wherein M is at least one element selected from the group consisting of a Group IV element and a Group XIV element, and the X satisfies 0.028≤X≤0.055.
