ODIf you place a scorpion under a UV black light, something unusual happens. It glows green! A few other animals exhibit this type of fluorescence as well — for example eastern fox squirrel bones glow pink. In this video we explain why scorpion exoskeletons fluoresce a slightly different color than squirrels bones.

USThe post features a short video demonstrating UV-induced fluorescence on a dental model fitted with braces, where a disclosing agent applied to the teeth glows green under blacklight to reveal plaque accumulation around the brackets and wires.
This technique, termed quantitative light-induced fluorescence (QLF), leverages the physics of light absorption and re-emission by fluorophores in plaque bacteria, enabling non-invasive detection; a 2020 Nature study found QLF-D visualises plaque with 84.5% accuracy compared to traditional agents.
Such visual aids highlight hygiene challenges with orthodontics, where plaque retention can rise by up to 3.5 times on bracket surfaces, underscoring the educational value of blending physics demonstrations with practical dental health insights.

CPThis isn't a render or simulation - this is the natural autofluorescence of a Monarch Butterfly (Danaus plexippus) chrysalis under a UV light! Even though it had only begun pupating days prior, many of the butterfly structures are already highlighted in fluorescence such as the wings and legs. To my surprise, the metallic markings don't really fluoresce, probably because of the structural shine and the carotenoid pigment responsible for the gold tint.
This is one of four caterpillars I raised this year, though only one of two that made it to maturity. Many caterpillars are prey whether for birds or animals, and the Monarch despite notoriety for being toxic, is not immune. The leading predator in my experience is a parasitic fly which tragically isn't noticeable until the caterpillar is nearly full sized.
All that said, when the migration and habitat of this amazing species is threatened, any that make it through to become butterflies is a very good thing and I'm happy my garden was able to provide some necessary habitat despite being deeply embedded in the suburbs!

BOChemiluminescence is the emission of light during a chemical reaction. Unlike fluorescence or phosphorescence, it doesn't require an external light source (like a UV lamp) to get started; the energy comes entirely from the breaking and forming of chemical bonds.
Think of it as a "cool" light—it releases very little heat because the energy is converted directly into photons.
How It Works
The process generally follows this path:
Reaction: Two or more chemicals react to form a highly unstable, "excited" intermediate.
Decay: The intermediate cannot stay in that high-energy state for long.
Emission: As the intermediate returns to its ground state, it releases the excess energy as light.
A classic example is the reaction of Luminol (C_8H_7N_3O_2) with an oxidizing agent. When catalyzed by something like iron (found in blood), it glows a vivid blue.

PHLaser Fluorescence in Calcite: this unique natural calcite specimen demonstrates strong fluorescence not only under UV but under longer wavelengths too. A high intensity 532nm green laser produces bright orange, a 445nm blue laser produces yellow light, and a near UV 405nm laser creates a pale whitish glow. The colorful glows comes from complex quantum mechanical behavior where photons are absorbed by trace amounts of Mn²⁺ (manganese in +2 ionic state) that take the place of calcium in the CaCO₃ lattice. The Mn²⁺ ions have special quantum levels that can absorb green photons and then transition to allow the energy to be released in the form of lower energy orange photons- the physics of fluorescence. ➡️ Follow the link in my profile for info on how to get such laser pointers, fluorescent mineral samples, and other amazing items featured here on @physicsfun #physics #physicsfun #physicstoy #electromagnetism #ultraviolet #uv #fluorescentminerals #mineralfluorescence #manganese #laserpointer #calcite #phosphorescent #fluorescent #science #scienceisawesome

THDiamond fluorescence is actually pretty cool. It means your diamond glows in UV light. Happens most commonly in natural stones but can occur in lab diamonds—often times colored ones since the same trace elements that make them colored also can cause fluorescence. Since blue cancels out yellow, it can even make diamonds look like a higher color grade than they are.

CHHappy #fluorescentFriday even though this is #Chemiluminescence 😎
In this experiment, I put my chemiluminescence experiment in water.
Chemiluminescence is a process where a chemical reaction produces light.
Chemiluminescence is different from fluorescence or phosphorescence because the glowing happens due to a chemical reaction, not from absorbing light. In chemiluminescence, a chemical reaction creates the excited state that produces light. This is the opposite of photochemical reactions, where light is used to power a chemical reaction. In chemiluminescence, light is made by releasing energy from a chemical reaction.

UNSold! I really love this Hyalite Opal from Namibia! The color on the piece is really amazing and the texture is really phenomenal! You don’t find them like this often and the daylight fluorescence along with the blacklight fluorescence is insane! $125! Available on our other page @over_100_dollar_gems
( this one is sold but we will be posting hundreds more over the next few months )
