Phosphorescence
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…

Fluorescence
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…

Photoluminescence
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…

Absorption, Photon
Photon absorption refers to the process by which an atom or molecule absorbs a photon and makes a transition to a higher energy level. This concept is at the heart of quantum physics and has a wide range of applications in various fields, including chemistry, biology, and materials science. (Please note that this process is intimately…
