本實驗中，以電子束微影術輔助，結合電漿蝕刻、金屬舉離製程製作不同之次微米結構，在改變金屬種類、圖騰結構與週期下，以光致螢光發光光譜，研究表面電漿共振與白光發光材料的耦合關係，並成功產生多發光波段表面電漿強化發光的結果。在理論上，則以金屬界面之色散關係、光柵耦合理論、有效吸收係數的計算，對表面電漿共振頻率，及其消散場間交互作用造成的偏移作一研究。
以下依實驗製作之不同結構，分成四部分討論：章節4-1中，討論由金、銀、鋁薄膜、改變厚度之銀薄膜試片，與發光材料(polyfluorene 共聚高分子)的耦合。金屬表面粗糙度是波向量減損的關鍵，而厚度控制介面表面電漿共振頻率的分裂；章節4-2、4-3中，討論銀薄膜披覆之具一維、二維微結構矽基板，與發光材料耦合。傳播型表面電漿，增加表面電漿共振釋放為光的效率，而微結構造成金屬的侷域性，使表面電漿共振產生藍位移；章節4-4中，控制銀粒子陣列週期、直徑，與發光材料耦合。圓柱粒子共振頻率的分裂，使表面電漿與發光波段吻合，結合區域型與傳播型表面電漿共振，觀測到多波段之發光強度增進，而金屬間消散場在近場距離的互相作用，也反應在發光光譜的相對強度變化。

Multiple surface Plasmon-coupling light emissions were successful demonstrated by photoluminescence observation. Different sub-micron structures were fabricated using standard electron beam lithography, ICP and lift-off process. In the theoretical approach, the dispersion relation between the metal and the dielectric interface, the wave vector loss by grating structures coupling and the effective absorption coefficient calculation by discrete dipole approximation were invested to realize the vibration of surface plasmon resonance frequency due to the interaction of evanescence fields between metal surfaces.
The followings were divided into four parts with different metal structures. In Chapter 4-1, gold, silver, alumni thick films and different thickness of silver films were coupled with the white light-emitting material, copolymer of polyfluorene. The wave vector loss was determined by the roughness of the metal surface and the surface plasmon resonance energy split while decreasing metal thicknesses. In Chapter 4-2, 4-3, one & two dimensional silvered sub-micron structures on silicon substrates were coupled with polyfluorene. The surface plasmon resonance energy was extracted into light efficiently with the assistance of the propagating surface plasmon mode. Multiple enhanced light emissions were caused by the V shape induced resonance frequency broadening with evanescence field interaction. Localized metal structures induced blue shift of resonance frequencies were observed while decreasing pattern periods. In Chapter 4-4, silver dot arrays of controlled periods and diameters were coupled with polyfluorene. The resonance frequency was matched with the emission band of active layer due to the resonance splitting caused by the cylinder structure. Dramatically multiple enhanced light emissions were observed as a result of localized & propagating surface plasmon mode combination. Relative intensity changes of emission spectra were found due to the interaction between evanescence fields in the near field range.
