Dual photonic-bandgap optical films towards the generation of photonic crystal-derived 2-dimensional chemical codes

Abstract

Chemical-oriented 2-dimensional (2D) optical codes were constructed for the first time by integrating bi-layer or bistriate-structure responsive photonic crystals (RPCs), which not only presents high information capacity in encoding processes, but offers a facile route to the detection of high performance sensors along with accurate analysis and anti-jamming performances.
