· Ba4Ge3Se9Cl2

Ba4Ge3Se9Cl2 is a mixed halide-chalcogenide semiconductor compound combining barium, germanium, selenium, and chlorine in a layered crystalline structure. This is a research-phase material studied primarily for infrared (IR) optical and nonlinear optical applications, where the combination of selenide and chloride ligands offers tunable bandgap and enhanced transparency in the mid-to-far IR region compared to single-anion chalcogenides. The material belongs to an emerging class of functional semiconductors designed for photonics and optoelectronics rather than conventional semiconductor electronics.

RoHS, REACH, and Prop 65 statuses are validated against official substance lists (ECHA SVHC Candidate List, OEHHA Prop 65, RoHS Annex II). Other regulations are estimated from composition and material classification. All screening is a starting point for due diligence — always verify with your supplier before making compliance decisions.
