Anodic Alumina Photonic Crystals as Refractive Index Sensors for Controlling the Composition of Liquid Mixtures

Abstract Photonic crystals based on anodic aluminum oxide films are examined as refractive index sensors for controlling the composition of water-alcohol liquid mixtures.The position of the reflectance maximum corresponding to the first photonic stop band is used as the analytical signal.Impregnation of a Body Wash photonic crystal with water-ethan
