What Fluids Glow under a Blacklight?

Blacklights emit ultraviolet (UV) light with a wavelength between 400 and 10 nanometers. This invisible light is just outside of the visible spectrum, so our eyes cannot see it. However, many materials can absorb UV light and re-emit it as visible light.

These materials will appear to “glow” under a blacklight. Fluorescent materials are the most common type of material that glows under blacklight. Fluorescent substances contain special molecules called fluorophores.

When UV light hits a fluorophore, it excites the molecule and causes it to emit visible light. Many household items contain fluorescent materials, including laundry detergent, highlighters, whiteboards, and some cosmetics. Other materials can also glow under blacklight.

Phosphors are substances that absorb energy from ultraviolet light or other forms of electromagnetic radiation and then re-emit that energy as visible light. Some phosphorescent materials can store energy for hours or even days before emitting it as visible light.

Is Tonic Water Luminescent?
