· CdS0.55Se0.45

CdS₀.₅₅Se₀.₄₅ is a cadmium chalcogenide semiconductor alloy that combines cadmium sulfide and cadmium selenide in a tuned stoichiometric ratio to achieve intermediate bandgap energy. This II–VI compound is engineered to bridge the bandgap between pure CdS (~2.4 eV) and pure CdSe (~1.7 eV), making it valuable for optical and optoelectronic devices that require sensitivity in the visible-to-near-infrared spectrum. The composition is notable in research and specialized manufacturing contexts for photon detection, scintillation counters, and tunable light-emitting applications where bandgap engineering is critical.

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.
