 note = {This dissertation reports the novel characterization technique based surface plasmon resonance (SPR) spectroscopy. First, solution-based fabrication of gold grating film for use as a SPR sensor chip, gold nanoparticles (AuNPs) grating films were fabricated by imprinting technique. The SPR measurements of this substrate were carried out on a SPR device in the grating–coupling configuration with an excitation source of He-Ne layer (λ = 632.8 nm) and multimode surface plasmon excitations were observed upon irradiation with white light. From both SPR measurements, imprinted AuNPs grating substrate provided strong SPR excitation signals. The sensitively shift upon organic thin film deposition were observed. Second, transmission surface plasmon resonance (T-SPR) enhancement by localized surface plasmon resonance of metal nanoparticles (i.e., AuNPs and silver nanoparticles (AgNPs)). AuNPs were directly deposited on gold grating surface. The growth mechanism of AuNPs on gold surface was investigated by UV-visible spectroscopy and SPR spectroscopy. The TSPR results show a possibility of hybrid excitation of localized and propagating surface plasmon. The T-SPR signal enhancement of this hybrid SPR substrate was observed while the multilayer films were deposited on its surface. Furthermore, distance-dependent SPR coupling between metal nanoparticles and gold grating surface was further study. The distance between AgNPs and gold grating surface was controlled by number of bilayers ultrathin film deposition. The distance-dependent T-SPR response of peak position and intensity showed distinctive changes when the intermediate layer was 10 bilayers (-17 nm) thick. This substrate was explored in switchable pH sensor. The T-SPR spectrum sensitively changed as the pH switched from acidic (pH 2) and alkaline (pH 12) conditions by the swelling/shrinking of the polyelectrolyte film between the AgNPs and the gold grating surface., 学位の種類: 博士（工学）. 報告番号: 甲第3924号. 学位記番号: 新大院博（工）甲第405号. 学位授与年月日: 平成26年3月24日, 新大院博（工）甲第405号},
