    • 近年來，光子晶體的特殊光學性質已被廣泛研究及討論。在本篇論文中，我們利用電沉積的方式，成功地製作出三維高排列性多孔洞結構。我們將三種不同的半導體，硒化鉛、硫化鎘和砷化鎵，用電沉積的方式滲入蛋白石晶體之空隙，再用氫氟酸將二氧化矽膠體球溶蝕掉，即可得半導體高排列性多孔洞結構。而電沉積時所使用的電解液濃度、電沉積時間、溫度、電流大小以及電沉積所選用的溶劑，也將在論文中做詳細的探討。經由掃描式電子顯微鏡及X光能量散佈光譜儀，我們可以得知樣品的真實結構及其組成原子比例。再經由紫外光-近紅外光光譜儀測量樣品的光學性質，我們可以得知硫化鎘多孔洞結構在光譜上約1350奈米時有明顯的吸收峰。

    Recently, there has been considerable interest in investigating the unique optical properties of three-dimensional photonic crystals, which consist of periodic dielectric structures with large index contrast. In this thesis, we used electrochemical deposition to fabricate 3D ordered macroporous structures. The films of three different semiconductors, PbSe, CdS, and GaAs, on the silica arrays were made using electrochemical depositions. Following by the removal of silica arrays, 3D macroporous structures made from those semiconductors have been obtained and these structures exhibited 3D periodicity and uniformity. Clear diffraction peaks at ~1350 nm of CdSe and CdS macroporous films were observed. The optical properties of the films will be discussed.
