· CdS0.65Se0.35

CdS0.65Se0.35 is a cadmium chalcogenide alloy semiconductor formed by substituting sulfur and selenium in a controlled ratio, creating a direct bandgap material intermediate between pure CdS and CdSe. This compound is primarily used in optoelectronic and photonic applications where tunable bandgap in the visible-to-near-infrared range is required, including photoluminescent devices, quantum dots, and photodetectors. Its main advantage over single-phase alternatives is precise bandgap engineering through composition control, making it valuable for researchers optimizing color-tuned LEDs, scintillators, and radiation detectors, though it remains less common in high-volume manufacturing due to toxicity concerns associated with cadmium.

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.
