碩士 === 逢甲大學 === 材料科學與工程學系 === 104 === This work is nvolved in the following major aspects, including (a) production of 3D photonic crystal templates with polystyrene (PS) microspheres on ITO glass substrates via electrophoretic self-aseembly (EPSA) techqiue, (b) synthesis of monodispsered silica microsphere by sol-gel process, (c) formation of ordered photonic crystal templaes of SiO2 microspheres on ITO glass substrates by EPSA roite, and (d) surface modification of photonic crystal temaplates of silica microspheres becoming hydrophobic by dip-coating method. The average size of SiO2 microspheres via sol-gel route was in a range of 200~300 nm. The wettability of templates of SiO2 microspheres on ITO glass substrates was achieved by dip-coating process, making the specimens being from hydrophilic into hydrophobic. Both photonic crystal templates of PS and SiO2 microspheres have tested to exhibit the photonic bandgap phenomena by UV-Vis spectroscopy. It is believed that the results obtained from this work will make some substantial contributions on developing the novel photonic devices involved in enhanced photonic bandgap properties.
