Phosphorescence

What's the difference between phosphorescence and fluorescence? What makes one type of material better suited for glow-in-the-dark applications than another? Read more in the link below!

Phosphorescence is a type of photoluminescence in which a substance emits light after being exposed to light energy (electromagnetic radiation). Unlike fluorescence, which is usually short-lived, phosphorescence can continue to emit light for a period of time after the initial exposure. The excited electrons tend to decay at a much slower rate. This can be as quick as a few microseconds and as…

Fluorescence

What makes some jellyfish glow? Read about fluorescence from the link below!

Fluorescence is a type of photoluminescence in which a substance absorbs light at a certain wavelength and then emits light at a longer wavelength, sometimes within the visible spectrum. This phenomenon is used in a wide range of applications, including biomedical imaging, chemical analysis, and materials science. One of the primary differentiating factors between fluorescence and other forms of…

Photoluminescence

Why do some things glow in the dark? Learn about photoluminescence in the link below!

Photoluminescence refers to the emission of light from a material after it has been excited by an external (photon) source, such as a laser. This process involves the absorption of a photon by the material, followed by the emission of that photon as visible light. Photoluminescence can be used to study the optical and electronic properties of materials at the nanoscale and has important…
