Title

Colour Engineering: Form Nature to Applications

Abstract

The most brilliant colours in nature are obtained by structuring transparent materials on the scale of the wavelength of visible light. By controlling/ designing the dimensions of such nanostructures, it is possible to achieve extremely intense colourations over the entire visible spectrum without using pigments or colorants. In this seminar, I will introduce some striking example of natural photonic structures and review our recent advances to fabricate bio-mimetic photonic structures using the same material as nature.
