Spectral properties of the high-silica porous glasses doped by silver halides

Photochromic quartz-like glasses were synthesized by an impregnation of the high-silica porous glasses with mixture of the Ag/Cu-Hal compounds (where Hal = Cl, Br, I; Cu2+ is sensitizer) from water-salt solutions. UV/VIS/NIR optical density and visible luminescence spectra of synthesized glassy composites have been obtained. It was shown that UV radiation of these materials causes luminescence of the silver centers in a visible spectral region (450-620 nm). The assumption that the photochromic quartz-like glasses based on the matrixes from silicate nanoporous glasses are promising materials for solar engineering has been stated on the grounds of obtained results.
