This chemical is a fluorophore, containing many aromatic groups and having the ability to absorb light and re-emit a new photon (fluorescence). There are other types of fluorescence that allow re-emission of light at higher energies or even the same energy but in this case the re-emitted light is at a lower energy. Because it is under a UV light, it absorbs the UV and the light that it re-emits will be visible to human eyes. Sadly, what we can see is only a very narrow band of the spectrum, still pretty awesome!
Well I went to see the great Gatsby for the second time with my friend today I would have talked and posted about it the first time but I forgot so here are some images that I found and a Quote if you have not seen or read the great Gatsby then go and do so. It’s one of the best, don’t you agree? Old sport.
