Chelating Agents for Quantum Dot Precursor Materials in Color Conversion Layers for Micro-LEDs

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 includes
• quantum dots 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,
• quantum dot precursor materials, wherein the quantum dot precursor materials comprise metal atoms or metal ions corresponding to metal components present in the quantum dots,
• a chelating agent bound to the quantum dot precursor materials, wherein the chelating agent is configured to inhibit aggregation of the quantum dot precursor materials,
• a photopolymer, and
• components of a photoinitiator that initiated polymerization of the photopolymer.
