If you're ever visiting Haarlem (if you're in Amsterdam, get on a train and forget about it, Haarlem is better), be sure to check out the Teyler's Museum. They have a massive room with all sorts of minerals (including the literal summitbof the Mont Blanc, so neither Italy nor France can lay claim to it) and off to the side of the entrance to that is this small dark room with all sorts of fluorescent and phosphorescent rocks. It's absolutely beautiful. Great museum overall, sort of a hodgepodge with old scientific instruments, minerals and art.
Here, just a hair west of Portland Oregon, you have the Rice NW Museum of Rocks and Minerals, with their rainbow room. They have lots of impressive displays, but the Rainbow Room is my favorite. That said, I love going there with my rockhounding lights and showing off some of their fluorescing rocks that are outside of the Rainbow Room. (Like, oh, nearly anything with uranium in it.)
Damn! I was in Haarlem last year and I actually walked by that place and gave it the cold shoulder because I thought is was some shlocky museum. Foolish me!
Fun fact: LEDs are an example of electroluminescent devices. Diodes emit light while conducting current because of the electrons getting excited and jumping to a higher energy level and subsequently releasing the energy as light, and LEDs are just a special kind of diodes made from materials that emit visible light instead of the infrared light emitted by regular silicon diodes. Furthermore, photovoltaic solar cells are also diodes, and they’re based on the inverse effect: when they absorb photons, the electrons get excited, which produces a potential difference which can produce a current.
Reminds me of the time I went to a mining museum on a fifth grade trip. We got to take a look at some really cool bioluminescent rocks. It was even cooler that we had the opportunity to keep some if we found any in a big huge pile. Orange and green are the colors my rocks grow. It's interesting learning more about those rocks and how they became that way

I used to have so many of those glow stars in my bedroom. They never held charges that well after a year or two. I wonder how they manufacture phosphorescence, and why it degrades like so. -I looked it up. Zinc sulfide powder, which came into popularity in the 1970’s. It’s relatively inexpensive, dissolves easily in water, and is approved for use in cosmetics.
I'm surprised that Rubies and Sapphires weren't mentioned as well. But since they weren't, I'll go ahead and share the fact that both floresce under a blacklight with Rubies florescing as a bright pink and Sapphires a much more subtle dark pink.💙💙
Hennig Brand was a _German_ pharmacist and alchemy. He was dead certain that the key to the Philosopher's Stone was locked away somewhere in human urine, so he collected his own, his wife's, and his associates' which he experimented on in numerous ways. Eventually he ended up with a glowing molten substance that crystalized into green, light emitting lumps that he called phosphorus after the Greek word for "light bringer." He wasn't sure what to actually do with it, so he just made it and showed it off as a novelty.
@@heatherswanson1664 To clarify for others: I am unaware if Nile Red has this fetish, lol, but he's a really entertaining chemist here on RUclips, he made some glow and the dark powder from scratch that looks really cool.
gneiss pun sorry this one is a little schist maybe some other time and galena insight from each other before the next 4500 Ma well it’s getting slate good niter
Galena is electroluminecent. I remember years ago I tried to make a diode from a piece and it lit up with a yellow light around the contact points. Basically making a crude LED.
When I was younger my parents replaced the tile in our kitchen to natural travertine. I discovered that the travertine floresced a bright yellow-green and even experienced phosphorescens for a second or so. Just saying you never know where stuff like this will show up!
@@tomf3150 indeed. I've also found a few sapphire, ruby, agat, and other various silicates that have fluorescence and or phosphorescence! Even a cheap uv light can help you find interesting specimens that glow.
@@tomf3150 I've found calcite and fluorite to be not that great with fluorescence. You need some fairly shortwave UV light to get them going, so just using a UV flashlight is not going to do it. One mineral I do like is willemite, which will glow under some fairly longwave UV light.
@Lindsey Dawes: tvtropes.org/pmwiki/pmwiki.php/Main/IsThatWhatTheyreCallingItNow Hey, what you do in the privacy of your own home is none of our business. Not kinkshaming, just wondering if any sparks were flying. ruclips.net/video/wu1UXCdyNo0/видео.html
So the what the kids call it today. In my day we called it getting your rocks off. I know, I'm a dirty old man, but I prefer the term "sexy senior citizen"
4:40 You can also see triboluminescence when you pull a tissue from its box (must have plastic holding up the tissue for this to work), or when you pull a trashbag from the roll.
in actuality, there are rocks that exhibit some of the properties discussed here. rocks, being a combination of various minerals, sometimes contain ones that say fluoresce, or are phosphorescent, like calcite, etc. they aren't the pure form of the mineral but are conglomerates of multiple minerals. yet they still display luminosity for one reason or another. also, geologists, when referring to both rocks and minerals, will just use the term rocks to describe material in general.
this is helpful, because I'm working on a story project using stones as parts of magic items or the magic items themselves. the one that actually makes since in a magical setting is the ones that glow after being hit with something, like if a wizard wants to know how far he has to go into a cave and isn't willing to be killed by, whatever monster lives inside, he can enchant the glowing rock, to return to his bag, after he throws it. another one that works, is the stone that glows when held, because if it's the right size the wizard or mage holding it, can use it like a flashlight.
As an avid collector of various photo luminescent minerals, this was definately SciShow for me. One of my favorite rocks, a large calcite crystal, exhibits both Phosphorescence under 254nm UV, orange Fluorescence under 365nm, and pink Fluorescence under 395nm. I strongly suspect it would exhibit Triboluminescence as well, but I don't want to smash my favorite rocks. I do wish you had shown some good calcite/willamite examples under normal white light, though. They can looks quite a bit like normal granite.
There's a cave around where I live that has a phosphorescent spot, it's on one side of a structure that looks like a big lizard/dragon. It's got the glowy bit round the eye and teeth area, it's super cool I love showing it off to visitors

That 'little asymmetry" needed for triboluminescence is called anisotropy, which is present in 27 of 32 types of crystal structures. This translates roughly to the majority of rocks. Some non-crystalline materials are also anisotropic.
I've been collecting fluorescent minerals for decades and find them fascinating. The deposits around Franklin,NJ are the very best in the world,but there are many other places where they're found. You need a long wave uv lamp like a black light,and a short wave uv,usually made from a mercury vapor germicidal lamp and a filter to screen out visible light,which can get pricey if you go big. One of my favorites in my collection is a 5-color specimen from Franklin: green willemite,red-orange calcite,purple hardystonite,yellow esperite and orange clinohedrite. What makes Franklin minerals so spectacular is two trace elements in just the right proportion:3% manganese and 1% lead activates the glow in a large number of the many types of minerals found there. I encourage everyone to look into them. Both scientifically and aesthetically,the subject can become obsessive. Trust me..
“If a rock you’re holding starts glowing, it doesn’t necessarily mean that you’re the Chosen One.” Yeah, it could mean that you’re secretly an alien adopted by human parents, and that you’re about to get a fatal dose of Kryptonite poisoning.
Triboluminescence also happens when you peel adhesive tape. I first noticed the phenomenon in a darkroom when removing the sticky tape at the end of a roll of photographic film.
Any time this channel talks about rocks/minerals/gems/crystals, they summon the neopagans and the Steven Universe crowd. And a few really cool geologists. Which one are you?
