在本論文中我們主要利用時變兆赫波研究含金奈米粒子發光溶液在兆赫波波段之光學性質，不同液體溶液樣品所對應到的折射率及介電常數的數值分析，當在GSH+Au之離子水溶液加上鑭系金屬離子形成發光強度更加突出的溶液之後，我們發現其在介於0.3~2.0 THz區間內的折射率與介電常數會隨著頻率增加而有下降的趨勢，且對應數值大小會較GSH+Au離子之水溶液還小。

In this thesis we mainly do research about optical properties of luminous solution that has gold nanoparticles in Terahertz spectral region using terahertz time-domain spectroscopy and data analysis of different solution samples corresponding to refractive index and dielectric constant. After adding rare earth elements to the ionic solution of GSH+Au to form a solution that has a higher light intensity, we found that the refractive index and dielectric constant in the region between 0.3~2.0 THz will decrease as the frequency increases. In addition, the corresponding values will be less than the ionic solution of GSH+Au.
