· Cd1Se0.45S0.55

Cd₁Se₀.₄₅S₀.₅₅ is a cadmium chalcogenide semiconductor alloy combining cadmium selenide and cadmium sulfide in a mixed-anion structure. This material is primarily investigated in optoelectronic research and represents a tunable bandgap compound within the II-VI semiconductor family; it bridges the direct bandgap characteristics of CdSe and the wider bandgap of CdS, making it relevant for photonic applications where bandgap engineering is required. Historical applications include photovoltaics, photodetectors, and light-emitting devices, though environmental and regulatory constraints on cadmium compounds have limited modern industrial deployment in favor of cadmium-free alternatives like perovskites and III-V semiconductors.

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.
