· Se1 Cd1

Cadmium selenide (CdSe) is a II-VI direct bandgap semiconductor compound commonly used in optoelectronic and photonic applications. It is valued for its tunable bandgap in the visible-to-near-infrared spectrum, making it suitable for light-emitting devices, photodetectors, and quantum dot applications where wavelength control is critical. CdSe is notable for its high photoluminescence efficiency and strong light absorption, though engineers must account for toxicity considerations and material stability when selecting it over less-toxic alternatives like cadmium-free perovskites or 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.
