  2. Phosphorescence - Wikipedia

    en.wikipedia.org/wiki/Phosphorescence

    Some examples of glow-in-the-dark materials do not glow by phosphorescence. For example, glow sticks glow due to a chemiluminescent process which is commonly mistaken for phosphorescence. In chemiluminescence, an excited state is created via a chemical reaction. The light emission tracks the kinetic progress of the underlying chemical reaction.

  3. Triboluminescence - Wikipedia

    en.wikipedia.org/wiki/Triboluminescence

    A diamond may begin to glow while being rubbed; this occasionally happens to diamonds while a facet is being ground or the diamond is being sawn during the cutting process. Diamonds may fluoresce blue or red. Some other minerals, such as quartz, are triboluminescent, emitting light when rubbed together. [19]

  4. Blue bottle experiment - Wikipedia

    en.wikipedia.org/wiki/Blue_bottle_experiment

    The aqueous solution in the classical reaction contains glucose, sodium hydroxide and methylene blue. [14] In the first step an acyloin of glucose is formed. The next step is a redox reaction of the acyloin with methylene blue in which the glucose is oxidized to diketone in alkaline solution [6] and methylene blue is reduced to colorless leucomethylene blue.

  5. Scientists find new exoplanet with atmosphere of 'glowing water'

    Also known as a 'hot Jupiter,' the exoplanet is so close to its star that temperatures at the top of the planet could even boil some metals.

  6. Milky seas effect - Wikipedia

    en.wikipedia.org/wiki/Milky_seas_effect

    Milky sea effect off the coast of Somalia in the Indian Ocean. Milky seas, sometimes confused with mareel, are a luminous phenomenon in the ocean in which large areas of seawater (up to 100,000 km 2 or 39,000 sq mi [1]) appear to glow diffusely and continuously (in varying shades of blue).

  7. Luminous paint - Wikipedia

    en.wikipedia.org/wiki/Luminous_paint

    Human eyes perceive this light as the unusual 'glow' of fluorescence. The painted surface also reflects any ordinary visible light striking it, which tends to wash out the dim fluorescent glow. So viewing fluorescent paint requires a longwave UV light which does not emit much visible light. This is called a black light. It has a dark blue ...

  8. Cherenkov radiation - Wikipedia

    en.wikipedia.org/wiki/Cherenkov_radiation

    Cherenkov radiation glowing in the core of the Advanced Test Reactor at Idaho National Laboratory. Cherenkov radiation (/ tʃ ə ˈ r ɛ ŋ k ɒ f / [1]) is electromagnetic radiation emitted when a charged particle (such as an electron) passes through a dielectric medium (such as distilled water) at a speed greater than the phase velocity (speed of propagation of a wavefront in a medium) of ...
