Photopolymer films were prepared for holographic recording and fabrication of multi-dimensional holographic fluorescent patterns. The photopolymer consists of a methacrylate epoxy monomer, photoinitiator, sensitizer, binder polymer, and polyanthracene (PAnt) as a fluorophore. The high diffraction efficiency of fluorescent photopolymer film was determined through a holographic recording system as 60% for a film of 85 μm in thickness. The optimized photopolymer film was applied to fabricate 2 dimensional patterns by laser interference lithography technique and rotation method. A 2-dimensional pattern was confirmed from a fluorescent microscope, which showed crossed pattern having a line width of 0.7 μm.
