Abstract : In order to demonstrate the feasibility of porous TiO2 multi-layers we address the possibility of color tuning of single thin films by means of varying the electrochemical anodization conditions (voltage and time). Ellipsometric data analysis using Bruggeman effective medium approximation confirms the interferometric nature of the sample color.
