Weba reason for the phosphorescence of the sea, a phenomenon now ascribed to the presence of certain luminous bacilli. In the vege-table kingdom, it is only algae and fungi, and a few bacteria which are phosphorescent, whilst in the animal kingdom phosphorescence is frequently found amongst Protozoa, jelly-fishes ( medusœ ), worms, WebPhosphorescenceis a type of photoluminescencerelated to fluorescence. When exposed to light (radiation) of a shorter wavelength, a phosphorescent substance will glow, absorbing the light and reemitting it at a longer wavelength. Unlike fluorescence, a phosphorescent material does not immediately reemit the radiation it absorbs.
