34 Facts About Fluorescence

What is Fluorescence?

Fluorescence is a fascinating phenomenon where certain substances absorb light or other electromagnetic radiation and then emit light. This process can be seen in everyday objects, scientific applications, and even in nature.

1. Fluorescence occurs when a substance absorbs light at one wavelength and emits it at a longer wavelength.
2. The term "fluorescence" comes from the mineral fluorite, which exhibits this property.
3. Fluorescent materials can glow under ultraviolet (UV) light, which is invisible to the human eye.
4. Fluorescence is different from phosphorescence, where the emitted light continues even after the excitation source is removed.

Natural Examples of Fluorescence

Nature is full of fluorescent wonders, from glowing creatures to vibrant minerals. Here are some natural examples that showcase this intriguing phenomenon.

5. Certain jellyfish species, like the Aequorea victoria, exhibit green fluorescence due to the presence of green fluorescent protein (GFP).
6. Fireflies produce light through a chemical reaction called bioluminescence, which is a form of fluorescence.
7. Some types of coral reefs glow under UV light, helping them attract symbiotic algae.
8. Scorpions fluoresce under UV light, making them easier to spot in the dark.
