Abstract:
A photocurable composition includes a nanomaterial selected to emit radiation in a first wavelength band in the visible light range in response to absorption of radiation in a second wavelength band in the UV or visible light range. The second wavelength band is different than the first wavelength band. The photocurable composition further includes one or more (meth)acrylate monomers, a thiol crosslinker, and a photoinitiator that initiates polymerization of the one or more (meth)acrylate monomers in response to absorption of radiation in the second wavelength band. A light-emitting device includes a plurality of light-emitting diodes and the cured photocurable 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.
