Opal is generally known for its fluorescence when put under UV light, but Mexican hyalite opal is unique in that it can also fluoresce in natural light.

It fluoresces bright green under black light due to the trace amounts of uranium contained within the opal layer.” The more uranium a hyalite deposit contains, the brighter it glows.

Additionally, OpalAI has been trained to leverage the unique way opal fluoresces under UV light, enhancing detection in low-light settings. OpalAI’s real-time visual detection capabilities ...

But under UV light they appeared green or cyan. The fur of the platypus absorbs UV (wavelengths of 200-400 nanometers) and re-emits visible light (of 500-600 nanometers), making it fluoresce.

Scientists in Australia analyzed a museum’s collection of mammals to see how many glow in the dark with a UV light turned on. Mayo Clinic. Other mammals that were found to illuminate under UV ...
