· K4 Te2 I12

K4Te2I12 is a layered halide perovskite semiconductor compound combining potassium, tellurium, and iodine elements. This is a research-phase material belonging to the halide perovskite family, which has attracted significant interest for optoelectronic and photovoltaic applications due to their tunable bandgaps and solution-processable synthesis routes. While still in development, materials in this class are being explored as alternatives to lead-based perovskites for solar cells, light-emitting devices, and radiation detection where compositional flexibility and lower toxicity are priorities.

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.
