title: Fluorescent grating patterns of photopolymer film containing ethylene glycol phenyl ether acrylate.
abstract: Photopolymer films containing photoreactive monomers in the presence of fluorescent polyanthracene were investigated for fluorescent grating pattern formation using a 3D holographic method. A monofunctional acrylate, ethylene glycol phenyl ether acrylate (PA), was used as the core monomer for the formation of the polymerization induced grating pattern. Photopolymer films were prepared from a mixture of PA and polyanthracene with a binder polymer and a photo radical initiator. The film's thickness was adjusted by the solution's composition to optimize grating pattern efficiency (>90%). The diffraction efficiency was increased in the presence of polyanthracene. Furthermore, the fluorescence intensity was more enhanced after grating formation. A vivid fluorescent gap electrode pattern with fine gratings was patterned, providing a new method for patterning organic thin films with distinct read-out processes.
