本論文研究主題分為兩部分，第一部份以水熱法在氧化鎵鋅薄膜上合成氧化鋅奈米線，探討材料微結構與光學特性。氧化鋅奈米線用硝酸鋅和六亞甲基四胺的水溶液合成，其濃度分別為0.02、0.04、0.06 M對應樣品A、B、C，掃描式電子顯微鏡影像顯示當合成溶液濃度提升時奈米線的直徑由約100奈米增加到300奈米，由於奈米線變粗而出現相鄰奈米線相互聚集現象。微光激發螢光光譜顯示濃度0.04 M所合成奈米線具有最強的近帶邊放光，並無明顯缺陷放光增強現象。
第二部分研究以機械式剝離法製備二維的硒化鉍薄片，探討其表面電漿共振對紫外光發光材料性質影響。紫外光發光材料有放光波長在350~360 nm的氧化鎵鋅薄膜與放光強度更強的六週期氮化鎵/氮化鋁鎵量子井發光二極體，掃描式電子顯微鏡影像呈現不同薄片形狀，原子力顯微鏡影像顯示剝離的硒化鉍薄片厚度在50至200 nm範圍，微光激發螢光光譜顯示並沒有觀察到硒化鉍薄片表面電漿具有增強紫外發光強度的性質。

There are two research topics in this thesis. The first is the study of variation of nanostructures and optical characteristics of zinc oxide nanowires (ZnO NWs) synthesized in aqueous-solution on gallium zinc oxide (GaZnO) thin films by hydrothermal method. The aqueous solution containing 1:1 ratio of various molar concentrations of zinc nitrate hexahydrate (Zn(NO3)2·6H2O) and hexamethylenetetramine (HMTA, C6H12N4). The molar concentration are 0.02, 0.04, and 0.06 M named sample A, B, and C, respectively. Scanning electron microscopic (SEM) images show that the diameter of the ZnO NWs is increased from about 100 to 300 nm when the concentration of synthetic solution is increased. The ZnO NWs with larger diameter tends to gather together. In micro-photoluminescence (micro-PL) spectra, the strongest near energy bandgap emission is observed in the sample with ZnO NWs having synthesized concentration of 0.04 M and without enhancement of defect-related light emission.
The second research topic is the study of preparing two-dimensional bismuth selenide (Bi2Se3) thin flakes having surface plasmonic behaviors by mechanical exfoliation techniques on ultraviolet (UV) light emitting materials. UV light-emitting materials with luminescence wavelength 350~360 nm include gallium zinc oxide (GaZnO) films and six periods GaN/AlGaN quantum well light-emitting diode have stronger UV emission intensity than GaZnO films. Scanning electron microscope images demonstrate the variety of shape of thin flakes. The thickness of thin flakes range from 50 to 200 nm estimated from atomic force microscope measurements. There is no observation of UV light emission intensity enhancement of UV light-emitting materials capped with Bi2Se3 thin flakes in micro-PL spectra.
