Bioluminecence , or a symbiotic arraignment between an animal and a bacteria, is a natural light source given off by a living organism.

Bioluminescence is a source of light similar to phosphorescence. Both types of light emission involve the release of energy in the form of visible light, with phosphorescence having a longer decay time than bioluminescence.
Phosphorescence is similar to fluorescence in that both involve emission of light by materials after they have absorbed energy. The main difference is the time scale: fluorescence is immediate, while phosphorescence has a delay before light is emitted.
Phosphorescence and fluorescence are both types of light emission, but they differ in how long they last. Fluorescence is a quick emission of light that stops as soon as the light source is removed, while phosphorescence continues to emit light for a period of time after the light source is removed.
Fluorescence and phosphorescence are both processes where a substance absorbs and then emits light. The key difference is in the timing of the light emission. Fluorescence happens almost immediately after the substance absorbs light, while phosphorescence involves a delay in the emission of light, which can last from milliseconds to hours.
Becquerel was interested in phosphorescence because it involves materials that emit light after being exposed to a source of energy, such as sunlight or electricity. He wanted to better understand this phenomenon and its underlying mechanisms, which ultimately led to his discovery of radioactivity.
Phosphorescent light sources convert electrical energy into light energy through a process called phosphorescence. When the phosphor material in the light source absorbs energy from an external source, such as electricity, it temporarily stores this energy and then releases it as light over an extended period of time. This delayed emission of light is what gives phosphorescent materials their characteristic glow after the initial energy source is removed.
