- Abstract
Zirconium (Zr) is a rare metal widely used in aerospace and military applications. However, its single color does not meet the requirements of camouflage and aesthetics. Here, a series of ultrathin structural colorations of Zr by coating it with a one-step anodization procedure were realized. Tunable colors of ultrathin zirconia (ZrO2) films can be obtained by adjusting the anodization time and can be tuned throughout the entire visible range. The structural color could endure 30,000 s of rinsing tests, 400 °C heat resistance tests, and over 480 h of intense ultraviolet irradiation. Zr/ZrO2 films may have potential in color displays, camouflage, and anti-counterfeiting technology.
