CPC H01L 33/504 (2013.01) [H01L 27/156 (2013.01); H01L 33/005 (2013.01); H01L 33/06 (2013.01)] | 16 Claims |
1. A light-emitting device comprising:
a plurality of light-emitting diodes that includes a first multiplicity of light-emitting diodes and a second multiplicity of light-emitting diodes, each light emitting diode of the plurality of light emitting diodes configured to emit radiation in a wavelength band in the UV range;
a first cured composition in contact with a surface through which radiation is emitted from the first multiplicity of the light-emitting diodes, wherein the first cured composition includes
a first photopolymer, and
a blue photoluminescent material that is free of quantum dots and selected to emit blue light in response to absorption of the radiation in the wavelength band from each of the light-emitting diodes of the first multiplicity of light-emitting diodes; and
a second cured composition in contact with a surface through which radiation is emitted from the second multiplicity of light-emitting diodes, wherein the second cured composition includes
a second photopolymer, and
quantum dots embedded in the second photopolymer and selected to emit red or green light in response to absorption of the radiation in the wavelength band from each of the light-emitting diodes of the second multiplicity of light-emitting diodes.
