Abstract
We propose the novel method for fabricating photonic crystal microparticles with internal woodpile structures by combining the hot-embossing process and prism holographic lithography (HL)[1]. Hot-embossing process using PDMS elastomeric mold define the micron-sized disks. These microarrays have internal woodpile structure with various reflectance peak position by controlling exposure time during prism HL. Using reactive ion etching to remove residual layer and dissolution of a pre-coated sacrificial layer[2], we can finally obtain free-floating photonic crystal microparticles that were released from the substrates. Owing to the porous structure of these free-floating HL microparticles, they exhibit highly enhanced fluorescence intensity and sensitivity of surface-enhanced Raman scattering (SERS) which suggest various applications [3-5].
