Low-cost sensing platforms based on tunable 1D photonic crystals integrated with organic light-emitting diodes and photodetectors
MetadataShow full item record
Herein, we present an innovative detection platform based on utilizing one-dimensional photonic crystals (ID PCs) as responsive multilayers for intensity modulation of narrow-band light sources, namely, organic light-emitting diodes (OLEDs). The tunable range for the stop band modulation lies in the visible region and can thus be detected in a straightforward fashion by a visible-light photodetector or an image sensor (CCD). We propose a route towards the bottom-up assembly of a fully functional, integrated miniature platform with a resolution exceeding the capabilities of most commercial spectrometers, and show temperature, humidity and chemical analyte detection.
