· Sr4 I8

Sr4I8 is an inorganic semiconductor compound composed of strontium and iodine, belonging to the halide perovskite family of materials. This material is primarily investigated in research settings for optoelectronic and photovoltaic applications, where halide perovskites show promise as alternatives to traditional semiconductors due to their tunable bandgaps and solution-processable synthesis. Sr4I8 is notable within the halide perovskite landscape for exploring how different metal cations (in this case strontium rather than the more common lead or tin) influence electronic properties and stability—making it relevant for researchers developing next-generation solar cells, light emitters, and radiation detectors with improved performance or environmental profiles.

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.
