本論文為研究能控制顏色變化的太陽能選擇性吸收膜，我們僅用一種材料製成多層膜，選擇鋁靶材並使用磁控濺鍍方法，在腔體內通入不同的氮氣量，基於氮化鋁的折射率會有不同變化的特性，使其可以製成多種不同的基材，其中我們選用 、 作為高低折射率材料，透過調整多層膜最外層 的厚度來控制顏色的變化，並量測多層膜的反射率光譜圖。 從反射率的光譜可發現隨著變動層厚度增加，可見光區的波包會向長波偏移，可以藉此來控制顏色。將光譜代回函數運算後可得到不同厚度的吸收率，吸收率的效果幾乎都接近90%，而輻射率低於3%。最後可得多種顏色變化的選擇性吸收膜。 ;In this thesis, colored solar selective absorbing films have been designed and fabricated. We use only one material, aluminum, for the sputtering deposition process, and fill different amounts of nitrogen to obtained variety multi-layer film of aluminum nitrogen. The refractive index and extinction coefficient depend on the content of nitride. We choose AlN-14%、AlN-18% as high and low refractive index material and adjusted the thickness of the outermost AlN-18% layer to contract the appearance of color. Then we measured the reflectance spectra of multi-layer film to calculate the absorption and emission. For calculating the absorption of the stacks including different thickness, we substituted spectral reflectance into equations. The result of absorbance is close to 90% and the emittance is less than 3%. The colors located on CIE chromaticity diagram is not much difference from actual samples. That indicates the color control is feasible.
