About the seminar:

Photonic crystals (PCs) with structural color leverage nanoscale periodicity to produce tunable and pigment-free optical effects with applications in sensing, coatings, and optical encryption. By eliminating the need for traditional dyes or pigments, these materials offer a more sustainable approach to color generation. However, achieving structural color across the full visible spectrum using block copolymer (BCP) PCs remains a significant challenge due to the limited tunability of self-assembled periodicities. This seminar introduces a practical strategy for creating BCP PC inks with fully tunable structural colors across the visible spectrum using solution blending and selective swelling, which enable precise nanoscale control over domain size.
