Chelating agents for quantum dot precursor materials in color conversion layers for micro-leds

A method of fabricating a light-emitting device, the method comprising:

• ejecting a photocurable composition onto an array of micro-LEDs that are integrated with backplane circuitry, wherein the photocurable composition includes quantum dots,
• quantum dot precursor materials that comprise metal atoms or metal ions corresponding to metal components present in the quantum dots,
• mono-thiol, di-thiol, thiocarbamate, dithiocarbamate, thiocarbonate, or thiourea,
• one or more monomers, and
• a photoinitiator;
• activating a plurality of micro-LEDs from the array of micro-LEDs to illuminate the photocurable composition over the plurality of micro-LEDs with light in a second wavelength band in the UV or visible light range that causes the photoinitiator to initiate polymerization of the one or more monomers and causes the quantum dots to emit light in a different first wavelength band in the visible light range;
• and
• removing an uncured portion of the photocurable composition from the array of micro-LEDs.
