Claim 0:
1. A method of forming a color filter for an optoelectronic device having a blue light source, the method comprising:
depositing an ink composition on a substrate that is in the optical path of the blue light source; and
curing the ink composition into a solid film, the ink composition comprising:
10 wt. % to 94.99 wt. % di(meth)acrylate monomers or a combination of di(meth)acrylate monomers and mono(meth)acrylate monomers;
4 wt. % to 10 wt. % multifunctional (meth)acrylate crosslinking agent;
1 wt. % to 50 wt. % red-emitting quantum dots or green-emitting quantum dots; and
0.01 wt. % to 85 wt. % of a blue light-absorbing material, the blue light-absorbing material characterized in that it preferentially absorbs blue light relative to red light or green light, wherein the solid film has an optical density, at a wavelength of 450 nm, of at least 1.0.
