Photonics: Transfer of 1D Photonic Crystals via Spatially Resolved Hydrophobization (Small 12/2021)

In article number 2007864, Bettina V. Lotsch and co-workers report a facile transfer of 1D photonic crystals and patterns thereof to arbitrary substrates by applying a sacrificial layer approach combined with spatially resolved amine intercalation for hydrophobization. Post-transfer modification such as amine exchange or heat treatment allow an adaptive control of the sensing properties of the photonic crystals thus enlarging application possibilities.
