Abstract: A light emitting device includes a light emitting diode configured to emit blue or ultraviolet radiation incident photons, a color conversion material located over the light emitting diode and configured to absorb the incident photons emitted by the light emitting diode and to generate converted photons having a longer peak wavelength than a peak wavelength of the incident photons, and at least one light extracting feature located between the light emitting diode and the color conversion material.

Abstract: A light emitting device includes a backplane, first, second and third light emitting diodes located on the backplane, a first patterned metamaterial lens containing first nanostructures located over the first light emitting diode, a second patterned metamaterial lens containing second nanostructures located over the second light emitting diode, and a third patterned metamaterial lens containing third nanostructures located over the light emitting diode. A configuration of the first nanostructures differs from a configuration of the second nanostructures, and a configuration of the third nanostructures differs from the configurations of the first and the second nanostructures.

Abstract: A light emitting device includes a first optical cavity bounded by cavity walls, a first light emitting diode located in the first optical cavity and configured to emit blue or ultraviolet radiation first incident photons, a first color conversion material located over the first light emitting diode and configured to absorb the first incident photons emitted by the light emitting diode and to generate first converted photons having a longer peak wavelength than a peak wavelength of the first incident photons, and a first color selector located over the first color conversion material and configured to absorb or reflect the first incident photons and to transmit the first converted photons.
