· Cd2 S2

Cd₂S₂ is a cadmium sulfide-based semiconductor compound belonging to the II-VI semiconductor family, known for its direct bandgap and photosensitive properties. This material finds application in optoelectronic devices including photoresistors, photodiodes, and radiation detectors where its light-responsive characteristics are leveraged; it is also investigated for thin-film solar cells and scintillation detection systems. Cadmium sulfides are valued for their tunable optical properties and historical use in early photomultiplier tubes, though modern applications must account for cadmium toxicity regulations in many regions, making alternative II-VI or perovskite semiconductors increasingly preferred for new designs.

Export Control

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.
