· JVASP-5794· Ag3PSe4

Ag3PSe4 is a ternary silver phosphoselenide compound belonging to the metal chalcogenide family, combining silver with phosphorus and selenium in a fixed stoichiometric ratio. This is a research-phase material investigated primarily for optoelectronic and photovoltaic applications due to its semiconducting properties and direct bandgap characteristics. While not yet established in mainstream industrial production, materials in this compound class show promise as alternatives to conventional semiconductors in specialized photonic devices, nonlinear optical systems, and emerging thin-film solar technologies where the combination of silver and chalcogen elements offers tunable electronic and optical properties.
