Claim 17:
18. A light-emitting device comprising:
a plurality of light-emitting diodes; and
a cured composition in contact with a surface through which radiation in a first wavelength band in the UV or visible light range is emitted from each of the light-emitting diodes, wherein the cured composition comprises:
a nanomaterial selected to emit radiation in a second wavelength band in the visible light range in response to absorption of the radiation in the first wavelength band from each of the light-emitting diodes; and
a photopolymer comprising a thiol crosslinker, wherein the nanomaterial is embedded in the photopolymer, and wherein the thiol crosslinker is aliphatic or aromatic, and wherein the thiol crosslinker comprises i) a mono-thiol, and the mono-thiol comprises ethanethiol, propanethiols, butanethiols, pentanethiols, thiophenols, thioacetic acid, glutathione, cysteine, mercaptoethanols, 2-mercaptoindole, furan-2-ylmethanethiol, 3-mercaptopropane-1,2-diol, 3-mercapto-1-propanesulfonic acid, 1-hexadecanethiol, or pentachlorobenzenethiol, ii) a 1,1-dithiol, and the 1,1-dithiol comprises methanedithiol, 1,1-ethanedithiol, or 1,1-cyclohexanedithiol, or iii) the thiol crosslinker comprises a 1,3-di-thiol, and the 1,3-dithiol comprises dihydrolipoic acid.
