本研究利用磁控濺鍍以及陽極氧化法在單晶藍寶石基板上製作具有奈米孔洞陣列結構的氧化鋁薄膜(AAO)，並在其表面沉積金屬錫與一氧化錫來改變可見光的透射和反射行為，造成原本是無色透明的藍寶石試片顏色改變，為後續應用的延伸作為基礎。
實驗以單晶藍寶石作為基板，利用磁控濺鍍法在其表面濺鍍一層金屬鋁薄膜，接著以磷酸與草酸兩種不同的電解液利用陽極氧化法將鋁薄膜轉化成具有奈米孔洞陣列的氧化鋁。然後將不同比例的金屬錫利用磁控濺鍍法沉積在其表面並將其退火成氧化亞錫。在薄膜結構鑑定方面利用X光繞射儀、場發掃描式電子顯微鏡以及奈米壓痕儀等分析工具鑑定材料，在薄膜電性方面利用四點探針測量鋁膜片電阻以判定薄膜品質，並利用百格測試法測量薄膜於基材的附著度。最後利用可見光譜儀量測試片在陽極氧化後、濺鍍錫後與錫退火成氧化亞錫後的穿透和反射的可見光譜變化，與其在肉眼觀察下的顏色做對照。
經由百格測試與奈米壓痕儀量測下得知，在工作氣壓為3 mTorr下的鋁薄膜擁有最佳附著度。透過場發掃描式電子顯微鏡的測量下得知，由草酸形成之AAO孔洞大小約為50 nm，對於可見光的繞射現象表現並不明顯濺鍍錫時，錫原子幾乎僅沉積在其表面；而由磷酸形成的AAO孔洞孔徑約為200 nm，使得入射光在波長400 nm下產生相消性干涉，孔洞大小足以使錫原子沉積在孔洞內部。經由可見光光譜儀測量下得知，在其餘濺鍍參數固定下濺鍍5分鐘，錫原子的量足夠對於薄膜產生可見光的影響且不會完全封住AAO所形成之孔洞，並在形成氧化亞錫之後對於透射與反射光譜產生多個波峰的波型變化，於外觀亦產生明顯的顏色變化。

In this study, anodized aluminum oxide film (AAO) with nanopore arrays structure was fabricated on single-crystal sapphire substrate by magnetron sputtering and anodic oxidation. Tin and tin oxide were deposited on the surface to change the transmission and reflection of visible light , Making the colorless and transparent sapphire substrate color change, the extension of the application.
Through the adhesion cross-cut test and the nanoindenter measurement, we found that the aluminum film has the best adhesion at a working pressure of 3 mTorr. Through the field emission scanning electron microscope measurement, the AAO hole size formed by oxalic acid is about 50 nm, which is not obvious for the diffraction phenomenon of visible light. The tin atoms are almost only deposited on the surface when tin is sputtered. The pore diameter of AAO formed by phosphoric acid is about 200 nm, which makes the incident light destructively interfere with the wavelength of 400 nm. The size of the holes is enough to make the tin atoms deposited inside the holes. After the visible spectrum measured via known, sputtering under five minutes, the amount of tin atoms sufficient to modify the results of the visible spectrum and does not completely seal the holes, and forming a plurality of peaks generated stannous oxide to the transmission and reflection spectra Wave pattern changes, the appearance also had a significant color change.
