  2. Motivation 上帝造物充滿智慧，地球上有許多生物體，擁有無法用肉眼看出的奈米結構，也各自擁有令人嘆為觀止的特殊功用，當中以蝴蝶翅膀最讓人心曠神怡，其特殊的光子晶體結構，能透發出斑斕的色彩，炫彩奪目。陽極氧化鋁(AAO)此種自我組裝多孔性結構，可以由控制孔度尺寸讓光的折射改變，進而透發出不同顏色的光。

  3. Introduction of AAO What is AAO (Anodic Aluminum Oxide )? Anodization Al Al2O3(nanoporous structure) Merits: • Self-assembly • High aspect ratio • Uniform pore size • Uniform channel length • Easy fabrication Top View • schematic experimental • equipment of anodization. Cross Section: O. Jessenskyet al.,Appl. Phys. Lett. 72, 1173 (1998).

  4. ＊AAO Tech Chemical reaction Metal/Oxide interface: Oxide/Electrolyte interface: • Expansion of aluminum during anodic oxidation.

  5. I-t Curve of Anodization • Surface oxide grows • Initial pore froms • Steady state time

  6. Procedures • 將玻璃基板清洗乾淨。 • 利用E-beam Evaporator將Al蒸鍍於玻璃基板上。 • 調配Oxalic Acid(0.3M)以及PHOSPHO-RIC ACID(5wt%) 的水溶液。 • 準備好Power supply以及電鍍槽。 • 做陽極氧化處理。
