· Bi9O7.5S6

Bi9O7.5S6 is a bismuth oxysulfide semiconductor compound belonging to the mixed anion oxide-sulfide family. This is primarily a research-phase material being investigated for photocatalytic and optoelectronic applications, where the combined oxide-sulfide chemistry offers tunable electronic properties distinct from single-anion parent compounds. The material family is of interest for visible-light-driven catalysis and thin-film device applications where the narrower bandgap and enhanced charge carrier mobility of oxysulfides provide advantages over traditional metal oxides or sulfides alone.

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.
