Abstract:
1. A red photoresist with gold nanoparticles, comprising: acrylate monomers; a photo-polymerization initiator mixed with the acrylate monomers; a plurality of gold nanoparticles having a size from approximately 3 nm to approximately 50 nm, wherein the quantity of the gold nanoparticles is about 0.05-0.5 percent by weight; and a first organic surfactant and a second organic surfactant, each molecule of the first organic surfactant and the second organic surfactant having a terminal heteroatom group and at least one linear alkyl group, wherein the linear alkyl group of the first organic surfactant is C6-C12, wherein the linear alkyl group of the second organic surfactant is C12-C20, wherein the terminal heteroatom group binds to the surfaces of the gold nanoparticles, and the linear alkyl group disperses the gold nanoparticles within the acrylate monomers and the photo-polymerization initiator.
