· JVASP-106459· K2RbYI6

K2RbYI6 is a mixed halide perovskite ceramic composed of potassium, rubidium, and iodine. This material belongs to the family of inorganic halide perovskites, which are primarily investigated for optoelectronic and photovoltaic applications due to their tunable bandgap and ionic conductivity properties. The incorporation of multiple alkali cations (K and Rb) is typical of research aimed at stabilizing perovskite crystal structures and modulating electronic properties for energy conversion or radiation detection systems.

Regulatory Screening

Environmental

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.
