Fabrication of dual sensitive titania (TiO2)/graphene oxide (GO) one-dimensional photonic crystals (1DPCs)

- The preparation method of 1DPCs is a convenient and low-cost method.
- The stopbands of TiO2/GO 1DPCs can be tuned in full-color range.
- TiO2/GO 1DPCs have a dual responsiveness to organic solvents and pH.
