Abstract

Silver-dielectric composite films were produced by a biomimetic technique, using the bacterial strain Pseudomonas stutzeri AG259 as a precursor for sol-gel-type deposition. Heat treated films backed by a metal displayed pronounced spectral selectivity of a kind that makes them interesting for photothermal conversion of solar energy. The optical properties could be reconciled with the Bruggeman effective medium theory.
