· Ca1 Se1

Calcium selenide (CaSeequiv) is a binary compound semiconductor belonging to the II-VI semiconductor family, with a rock salt crystal structure similar to other alkaline-earth chalcogenides. This material is primarily of research and developmental interest for optoelectronic and photonic applications, where its wide bandgap and optical properties make it relevant for UV-to-visible emission devices, though it remains less commercially established than more mature II-VI semiconductors like CdSe or ZnSe. Engineers consider calcium selenide for specialized applications requiring environmentally benign alternatives to cadmium-based semiconductors, combined with its potential for quantum dot synthesis and thin-film photovoltaic research.

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.
