利用两步蒸发法制备的铝(Al)-银(Ag)复合金属岛(CMI)薄膜已被实现用作较短波长的一次写入(WO)光学数据存储介质。Al-Ag CMI薄膜对蓝光有较高的反射率，其共振波长在450-500 nm范围内。实验证实，当温度为200℃时，Al-Ag CMI膜的反射率显著降低。这表明，Al-Ag CMI膜可用作波长较短、存储密度较大的WO介质。
Aluminium (Al)-silver (Ag) compound metal island (CMI) films fabricated by using a two-step evaporation method have been realised for use as write-once (WO) optical data storage media for shorter wavelengths. The Al-Ag CMI films have a high reflectance for blue light as the resonance wavelength exists in the 450–500 nm range. It has been experimentally confirmed that the reflectance of the Al-Ag CMI film is significantly reduced by heating at a temperature of >200°C. This suggests that the Al-Ag CMI films may be useful as WO media for shorter wavelengths with larger storage density.
