    Abstract: 由於奈米金柱具有獨特的光學性質與良好的加工性,有望成為新一代高效能的奈米級的光學設備。此外,奈米金柱陣列的表面電漿共振效應在光學感應器上具有極大的潛力。過去奈米金柱的粒徑主要是利用TEM做分析,但TEM量測屬於小範圍上的分析,若利用小角度X光散射(SAXS)去分析,可以得到整體奈米金柱的粒徑的平均值。因此本研究主旨在以小角度X光散射(SAXS)去鑑定合成的奈米金柱,同時也能夠以此去辨別高分子模板控制奈米金柱陣列有序性。研究內容主要可以區分成兩個部分:奈米粒子的合成鑑定與高分子模板控制陣列。
    ;Due to nanorods of noble metals unique optical properties and facile processability, they have been highly potential and effective nanoscale optical devices nowadays. Plasmon coupling between nanorods in an array configuration shows great potential for optical sensing. In the past, size of AuNRs was identified with TEM which indicated local information. However, small-angle X-ray scattering (SAXS) can be used to obtain average of entire size of AuNRs. We aim to identify AuNRs and ordering arrays of AuNRs by SAXS. Our research includes two different parts as follows:
    1.Identify synthesis of gold nanorods:We synthesized AuNRs with different sizes by single and binary surfactant seeds-mediated growth methods. We were first group to estimate the size of AuNRs by small-angle X-ray scattering. Also, we compare it with Transmission electron microscopy and ultraviolet–visible spectroscopy.
    2.Template-Assisted Gold nanorod arrays with polymer template:We were first group to fabricate an array of AuNRs with diblock copolymer(BCP)template by utilizing electrostatic interactions between mPEG modify rods and an anionic surface. Moreover, we also controlled drying of AuNRs between a smooth surface and a PDMS microtextured stamp.
