Abstract
Organic ligand-capped quantum dots and curable ink compositions containing the organic ligand-capped quantum dots are provided. Also provided are thin films formed from the ink compositions.
Claims10
A photonic device comprising:
- a photonic device substrate;
- a crosslinked polymer film on the photonic device substrate, the crosslinked polymer film comprising:
- 50 to 90 wt. % crosslinked polymer chains comprising polymerized di(meth)acrylate monomers or a combination of polymerized di(meth)acrylate monomers and mono(meth)acrylate monomers;
- 1 to 10 wt. % multifunctional crosslinking agents linked to the polymer chains;
- and
- 20 to 30 wt. % quantum dots having ligands bonded to the polymer chains;
- and
- a filter layer that blocks light having wavelength less than an absorption wavelength or emission wavelength of one or more of the quantum dots.
