THE SCIENCE OF BIOFLUORESENCE

Scuba Diver Australasia + Ocean Planet - - Feature: A Fluorescent World -

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.
