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.
研究了在荧光聚蒽存在下含有光反应性单体的光聚合物薄膜,采用三维全息方法形成荧光光栅图案。使用单官能丙烯酸酯乙二醇苯基醚丙烯酸酯(PA)作为形成聚合诱导光栅图案的核心单体。光聚合物薄膜由PA和聚蒽与粘合剂聚合物和光自由基引发剂的混合物制备而成。通过溶液组成调节薄膜厚度以优化光栅图案效率(>90%)。在聚蒽存在下衍射效率提高。此外,光栅形成后荧光强度增强得更多。制备出了具有精细光栅的生动荧光间隙电极图案,为通过不同读出过程对有机薄膜进行图案化提供了一种新方法。
