· Cs2Ga2S5

Cs₂Ga₂S₅ is a ternary chalcogenide semiconductor compound composed of cesium, gallium, and sulfur, belonging to the family of wide-bandgap semiconductors used in optoelectronic and photonic applications. This material is primarily of research interest rather than established industrial production, investigated for its potential in infrared detection, nonlinear optical devices, and scintillation applications where its wide bandgap and sulfide composition offer advantages in UV-to-mid-IR wavelength ranges. Compared to more mature alternatives like GaAs or CdTe, cesium gallium sulfides remain largely experimental but are valued by researchers exploring next-generation detectors and frequency-conversion devices that require both wide transparency windows and radiation hardness.

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.
