Clay Bragg Stack Optical Sensors

Functional 1D photonic crystals are fabricated based on the clay Laponite and mesoporous oxide layers. Color-tunable clay Bragg stacks are sensitive to a wide range of analytes and show potential as intelligent optical devices for chemo-optical sensing applications.
