Abstract

A dynamic color visualization strategy was proposed based on ITO (Indium Tin Oxide)-BST (Ba0.5Sr0.5TiO3)-ITO multiple nanofilms. A black layer was capitalized on to absorb the incoherent scattered light and to enhance the contrast ratio of the reflected light. While the thickness of BST thin film changed from 100 nm to 140 nm, the peak wavelength of the reflected light shifted from 383.7 nm to 501.2 nm as the refractive index of BST thin film was set as 2.4. Meanwhile, the visualized color of the multiple nanofilms was changed from purple to turquoise. The measured reflected spectra fitted well with the simulation results based on Finite Element Method. The fabricated samples proved that the black layer played an important role in the contrast ratio increase.
