Abstract
The present disclosure provides a method for manufacturing a TiO2 crystalline metasurface, the method including: (S100) coating a substrate with a TiO2 sol-gel ink; (S200) arranging a mold having a concave nanopattern on the substrate coated with the TiO2 sol-gel ink to form an assembly; (S300) solidifying the TiO2 sol-gel ink inside the assembly; and (S400) after releasing the mold, performing a heat treatment on a TiO2 nanostructure to crystallize TiO2.
