利用磁控漸鍍法在c面氧化鋁基板上備製氧化鋅與氧化亞銅之超晶格結構。由於氧化鋅與氧化亞銅容易互相擴散，因此藉由改變氧化亞銅之沉積時間來改變厚度，尋得到較不易擴散的結構。在結構方面，穿透是電子顯微鏡及X光反射率，我們可以得到分層及是否有擴散的情形。而在光學特性上，利用光製螢光我們發現到有聲子共振輔助激子的效應，另外也有反斯托克的現象產生。

Superlattices with alternating layers of Cu2O and ZnO have been prepared by magnetron sputtering on (0001)-sapphire (Al2O3) substrates. The Cu2O is easier to diffuse into ZnO so that producing different thickness of each Cu2O layer by controlling the Cu2O deposited time becomes the great point of research. Transmission electron microscopy (TEM) and X-ray reflectivity (XRR) were used to observe the structural properties, the deposition and the diffusion of superlattices. There are some unique properties of energy gap, phonon-assisted resonance exciton and anti-Stoke's process of Cu2O and ZnO superlattices from the optical transitions of photoluminescence spectroscopy.
