AlCoZnNi 與Al透過共濺鍍去分析其機械特性、腐蝕特性以及其光學特性，並應用於LED 外封裝反射層的可行性。研究的材料包括Al25Co25Zn25Ni25、Al36Co22Zn21Ni21、Al45Co18Zn17Ni20、Al50Co16Zn17Ni17、Al60Co13Zn13Ni14、Al65Co12Zn12Ni11、Al81Co6Zn6Ni7薄膜，以及熱退火對Al50Co16Zn17Ni17、Al60Co13Zn13Ni14、Al65Co12Zn12Ni11光學特性的影響。
由於Al-Zn 本身存在相分離的特性，使得此材料有富鋁以及富鋅的雙層特性。透過機械特性以及耐腐蝕測試研究此材料，可以觀察到相分離的雙層結構以及高熵效應可以使硬度增加，在3.5 wt.%的NaCl溶液中，隨著Al含量的減少以及Co、Zn、Ni 鈍化金屬比例的增加會讓整體的腐蝕電位以及孔蝕電位有所上升，Al25Co25Zn25Ni25 的腐蝕電位以及孔蝕電位分別為 -0.77376 V和0.7 V，代表著高熵合金本身的高抗腐蝕特性。
研究Al50Co16Zn17Ni17、Al60Co13Zn13Ni14、Al65Co12Zn12Ni11反射率高於Au的光學特性以及其反射率的熱穩定性，可以發現經過RTA 200℃、300℃、400℃後，特別是Al60Co13Zn13Ni14、Al65Co12Zn12Ni11 在UVC波段的反射率甚至高於Al，也可以有效取代Al本身容易氧化以及退火過後的晶粒成長讓粗糙度上升進而讓反射率降低的因素。

The aim of this research makes a thorough inquiry into the mechanical properties, thermal stability, and corrosion behavior of AlCoZnNi (HEA1) and Al that were made from co-sputtering. Finding out the correlation between HEA1 characteristics and optical properties would be the main axis of this research.
The reflectance of Al65Co12Zn12Ni11 increased due to reduction of roughness by Sluggish diffusion effect from room temperature to 200 ℃, 300 ℃and 400 ℃ annealing about 60.02%, 69.31%, 67.87% and 66.54% at 280 nm in UV band respectively. Corrosion potential and pitting potential of HEA1 within -0.77376 V and 0.7 V respectively from the corrosion test after packaging in 3.5wt. % NaCl. Represent the high corrosion resistance of the high-entropy alloy.
Another breakthrough discovery of the spinodal decomposition caused by Al-Zn. The characteristic of this material was aluminum-rich and zinc-rich bilayer, that the period of the bilayer will increase also happened on the sputtering rate. The bilayer of spinodal decomposition and solid solution can enhance the mechanical properties. The hardness of Al45Co19Zn16Ni20 was largest about 12.86 GPa.
