zinc sulfide
Definition
Noun: A yellow to white crystalline fluorescent compound that occurs naturally as the minerals sphalerite or wurtzite and is used as a luminous pigment.
Usage
"Zinc sulfide" is a specific chemical compound. It is used as a singular, non-count noun when referring to the substance in general. * The phosphor screen was coated with zinc sulfide. * Zinc sulfide exhibits luminescence when exposed to certain types of radiation.
Examples
- The mineral sample was identified as zinc sulfide.
- Early radar screens used zinc sulfide as a key phosphor material.
- The purity of the synthesized zinc sulfide was confirmed by X-ray diffraction.
Advanced Usage
- Doped zinc sulfide: Refers to zinc sulfide with small amounts of other elements (activators) added to alter its luminescent properties.
- Copper-doped zinc sulfide is a common green phosphor.
- Zinc sulfide nanoparticle: Refers to particles of the compound on the nanoscale, which have unique optical and electronic properties.
- The research focuses on the quantum effects in zinc sulfide nanoparticles.
