· ZnS

Zinc sulfide (ZnS) is a II-VI compound semiconductor with a zinc blende crystal structure, commonly available in both cubic (sphalerite) and hexagonal (wurtzite) phases. It is widely used in optoelectronic and photonic applications where its wide bandgap and optical transparency in the visible and infrared regions are critical advantages. ZnS serves as a phosphor material in displays and lighting, as a window or lens material in infrared imaging systems, and in thin-film solar cells and LEDs, where its direct bandgap makes it preferable to wider-gap alternatives like ZnO for certain wavelengths.

Regulatory Screening

Environmental

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.
