Abstract: A method for dye-free coloring of one-time anodic aluminum oxide surface is revealed. First provide a substrate containing aluminum. The substrate containing aluminum is anodized once at room temperature. The anodizing process includes a step of applying a pulse signal on the substrate containing aluminum for a first period of time. Thus a porous aluminum oxide layer is formed on surface of the substrate containing aluminum. The pulse signal includes a part with positive voltage and a part with negative voltage. Then a metal layer is deposited on the surface of the porous aluminum oxide layer. The porous aluminum oxide layer has a first interference wavelength. Next perform a linear regression of the first interference wavelength versus the first period of time. The absolute value of the slope of the regression line obtained ranges from 1.8 to 38.5. The absolute value is positively correlated with the positive voltage.
