Abstract
A color photoresist with gold nanoparticles and color filters made therefrom are provided. The color photoresist with gold nanoparticles includes substituted acrylate monomers, gold nanoparticles (or clusters), surfactants and a photo-polymerization initiator. The color filter includes a polyacrylate, gold nanoparticles (or clusters) and surfactants. The gold nanoparticles (or clusters) can be dispersed in the color photoresist or the color filter by the surfactants.
