当在Al基底上的薄阳极氧化铝（AAO）膜通过化学气相沉积均匀地涂覆碳时，干涉色的饱和度显著增强，因此，涂覆的AAO膜呈现出明亮的颜色。这种显著的饱和度提高主要是由于碳沉积在AAO膜的纳米通道的内壁上，有效地屏蔽了来自AAO-Al界面的反射光。这种光亮的碳涂层AAO薄膜可用于耐候装饰，并有望成为纳秒激光脉冲的有效宽带光限幅器。
When a thin anodic aluminum oxide (AAO) film on an Al substrate is uniformly coated with carbon by chemical vapor deposition, the saturation of interference color is substantially enhanced and, as a result, the coated AAO film exhibits a brilliant color. Such remarkable saturation enhancement is predominantly due to the carbon deposited on the inner walls of nanochannels of the AAO film, which efficiently screens the reflected light from AAO–Al interface. The brilliant carbon-coated AAO film is useful for weather-resistant decorative purposes and holds promise as an effective broadband optical limiter for nanosecond laser pulse.
