THE SCIENCE OF BIOFLUORESENCE

On an atomic level, the fluorescent molecules of an organism absorb the tiny light particles, photons, of an external source such as a blue or UV light.

The electrons in the fluorescent molecules are excited by the photons and they are “bumped up” to a higher energy state. When the electrons decay back to their normal state, a photon of lower energy and longer wavelength is emitted, which manifests as different colours.
