Abstract

We have demonstrated the simple preparation of structurally colored composite films by stacking alternating Os and PB layers. Os has a much higher refractive index than PB, which causes the strong reflection at the interface between these two materials. Strong reflection colors were observed because of th e interference between the multi-layers. Active control of the reflection peaks was achieved by swelling the PB layers. From these results, we conclude that black thin layers enhance the reflection of structural colors.
