Yes, ultraviolet (UV) rays can produce fluorescence with zinc sulfide (ZnS). Zinc sulfide is a commonly used phosphor material that exhibits fluorescence when exposed to certain wavelengths of light, including UV light. When UV rays of appropriate energy strike the ZnS crystal lattice, the atoms within the lattice absorb the energy and transition to higher energy levels. Subsequently, the excited atoms release the excess energy in the form of visible light, resulting in fluorescence.
Zinc sulfide is often utilized in various applications, such as fluorescent lighting, cathode-ray tubes (CRTs), and luminous paints, due to its ability to emit visible light when stimulated by UV radiation. The emitted light can have various colors, depending on impurities or dopants added to the ZnS crystal lattice.
