| Summary: | 碩士 === 國立臺灣海洋大學 === 光電科學研究所 === 99 === Silver nanoparticles have been synthesized by method of heat chemical reduction of silver nitrate by ethanol. The samples have been characterized by UV/VIS absorption spectroscopy. The observation of main absorption peak exists at 410nm, due to Surface Plasmon Resonance (SPR) of silver nanoparticles. By changing the concentration of silver nitrate and heating time, we can obtain silver nanoparticles of various sizes. The reduction method has the advantage of being a relatively simple process of obtaining homogeneous silver nanoparticles.
