· K2 Ge2 Br6

K₂Ge₂Br₆ is an inorganic halide perovskite semiconductor compound composed of potassium, germanium, and bromine. This material belongs to the emerging family of lead-free halide perovskites under active research for optoelectronic applications, offering potential advantages in stability and toxicity compared to lead-based alternatives. While primarily in the research and development phase, K₂Ge₂Br₆ and related germanium halides are investigated for photovoltaic devices, X-ray scintillators, and radiation detection due to their semiconducting properties and relatively high atomic number composition.

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.
