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

Abstract

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.
