Application of anodized aluminum in photoelectric field

The photoelectric element is prepared by filling a fluorescent material in a microporous membrane of a porous membrane, and a functionalized membrane prepared by introducing Tb3+ into the porous membrane by a combination of immersion and heat treatment, and emitting green light under the action of an external electric field. The high luminescence intensity that can be obtained by such a functionalized porous membrane indicates that the functionalization of the porous membrane will become another new way to develop photovoltaic elements. Further, since the pore diameter of the porous film is extremely small, an ultrafine light-emitting element can be further developed. Electrolytic black, can also be used as optical instruments, camera extinction and other decorative uses.
