Abstract:
Embodiments of the invention include a light emitting structure comprising a light emitting layer. A first luminescent material comprising a phosphor is disposed in a path of light emitted by the light emitting layer. A second luminescent material comprising a semiconductor is also disposed in a path of light emitted by the light emitting layer. The second luminescent material is configured to absorb light emitted by the light emitting layer and emit light of a different wavelength. In some embodiments, one of the first and second luminescent materials may be bonded to the semiconductor structure.
