· Ce1 Se1

Cerium selenide (CeSe) is a rare-earth semiconductor compound belonging to the cerium chalcogenide family, characterized by the coupling of a lanthanide metal with a group XVI element. This material is primarily investigated in research and emerging applications for optoelectronic and thermoelectric devices, where its narrow bandgap and rare-earth properties offer potential advantages in infrared detection, photovoltaics, and solid-state cooling systems. Engineers consider CeSe when conventional semiconductors (Si, GaAs) cannot meet requirements for specific wavelength response or when rare-earth-driven electronic properties are essential, though it remains largely in the development phase outside specialized research contexts.

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.
