· Ba4 Zn2 Ag4 Se4 O4

Ba₄Zn₂Ag₄Se₄O₄ is an oxychalcogenide semiconductor compound combining barium, zinc, silver, selenium, and oxygen—a mixed-anion material class that bridges conventional oxides and selenides. This is a research-phase compound studied for its potential in optoelectronic and photonic applications; the silver and selenium content suggests interest in photoconductivity, nonlinear optical response, or photocatalytic properties, while the layered oxychalcogenide structure offers tunable band gaps compared to single-anion alternatives.
