Abstract
A recording material for holograms includes a metal oxide porous body with an oxygen donor substance in the pores. In addition, a method manufactures a recording material for holograms that include a metal oxide porous body with an oxygen donor substance in the pores. The method includes forming a metal oxide porous body from a metal oxide precursor, and supplying an oxygen donor substance to the pores of the metal oxide porous body.
Claims21
A recording material for holograms comprising a metal oxide porous body, the metal oxide porous body including a plurality of pores defined by an outer boundary of the metal oxide porous body and the porous maintaining oxygen donor substance beyond the outer boundary of the metal oxide porous body.
A method for manufacturing a recording material for holograms comprising a metal oxide porous body provided with an oxygen donor substance in the pores which comprises:
- a step of forming a metal oxide porous body from a metal oxide precursor, and
- after the step of forming said metal oxide porous body, a step of supplying an oxygen donor substance to the pores of said metal oxide porous body.
