Abstract:
We propose a thermo- and hygro- tunable optical filter based on the nanoparticle-based TiO2/SiO2 one-dimensional photonic crystals, dubbed Bragg stacks. The tunability is achieved by the utilization of 1D Bragg structures as optical filters capable of changing their refractive properties when in contact with an analyte of interest or when exposed to external stimuli such as temperature, humidity, etc. The change can be detected by measuring the reflection or transmission of different kinds of li...     »
