Abstract
A method for forming a multilayer thin film having a crystalline metal oxide layer, the method including: encapsulating at least one encapsulated layer of the multilayer thin film in a wet chemical composition by wet chemical methods; and crystallizing the wet chemical composition by microwave hydrothermal treatment to form a crystalline metal oxide layer encapsulating the at least one encapsulated layer of the multilayer thin film.

A method for forming a multilayer thin film comprising a crystalline metal oxide layer, the method comprising:
- encapsulating at least one encapsulated layer of the multilayer thin film in a wet chemical composition by wet chemical methods;
- and
- crystallizing the wet chemical composition by microwave hydrothermal treatment to form a crystalline metal oxide layer encapsulating the at least one encapsulated layer of the multilayer thin film,
- wherein the multilayer thin film produces an omnidirectional structural color.
A method forming a multilayer thin film comprising a reflective core layer, a crystalline metal oxide layer encapsulating the reflective core layer, a first layer extending across the crystalline metal oxide layer, and a second layer extending across the first layer, wherein:
- the crystalline metal oxide layer is formed by:
- encapsulating the reflective core layer in a wet chemical composition by wet chemical methods;
- and
- crystallizing the wet chemical composition by microwave hydrothermal treatment to form a crystalline metal oxide layer encapsulating the reflective core layer;
- and
- the multilayer thin film produces an omnidirectional structural color.
