Thanks for the awesome video. Interestingly, the Stewart Semple ‘LIT’, which you bought from the USA (13:06) is actually made by a British Artist who started making his own pigments in response to one particular artist being given sole rights to use Vantablack (a nano carbon texture that at the time was described as the ‘blackest black’). Stewart disagreed with this monopoly, and LIT has been one of the products he’s created since.

Adding on to that, the differentiation between fluorescence and phosphorescence can only be made with lifetime measurements of excited states. Therefore, if you can't for sure say which it I'd, you should call effect like these "Luminescence" since that is,.Ad the overarching name, always correct.

When I bought my house a couple years ago, which included a beautiful inground swimming pool, I found that in the process of the pool being surrounded with concrete, had "glow in the dark" stones embedded in the finished surface. So during the day, these stones would "charge" in the sunlight, and after sunset would glow. Not bright enough to read by, but certainly helpful in walking around without missteps.

You can produce very pure aluminum nitrate with nitric acid by first dissolving a few milligrams of clean mercury into the acid. A tiny bead should be sufficient. The aluminum reduces the mercury ions to mercury, which amalgamates with the foil surface, preventing its passivation. Aluminum amalgam is very reactive, so add ice to the acid before adding the foil and use a cooling bath to prevent runaway. Also, use a molar excess of foil so that the mercury can be filtered off, as it will adhere to the unreacted aluminum.

@@mars1450 Yes. And...also but, Society is the only place that institution can exist, as per your second point about dialectics. Meaning that a convention and system for training humans to co-exist with that institution is definitely necessary. I.e. Culture... As to learning literature, music, rhetoric, etc. We are oxytocin driven animals, that evolved with mouths. We already hung out in groups and learned by imitation and mimicking. Attaching layered memetics to the utterances over time, was bound to happen. Which is, I guess, slightly the same as your point. My point... We have to broadcast teach in hopes of, at least, creating good mimics. The yard stick analogy, cut it in half, and then that half, half again. The bottom portion are people who either don't get it or don't care to. But they still mimic... Then the doers, then the thinkers. My whole point is about meta cognition and the layered ability to see teaching and learning from a mind set that is above the individual, or outside of ones "self." When you return to the cave, it is a shot in the dark, but you still do it. Because honestly even with what feels like, sounds like, looks like, two humans communicating... the other minds problem says that we will never experience another chemistry or brain wiring. It's all for ourselves, but if the conventions and the experiences those conventions elicit are in sync enough to guarantee a certain response from the other, then it doesn't matter that it's arbitrary. But yeah, learning is individual.

I played with fluorescent fishing lures as a child; they were a flat bit of plastic that glowed green. I'd 'charge' them with a lamp, then watch the glow slowly fade. On a cold day, I discovered that static-discharges would make 'dark lightning' patterns in the glowing plastic of the lure! I would charge the lure with a lamp; sparks passing through the lure made a brief bright streak that 'used up' the stored light energy! This resulted in fine dark lines appearing on the glowing background. Lichtenberg patterns on the cheap? Heating the glowing plastic made it brighter, but the glow fades faster. Always thought they'd make a novel 'short-term memory' for a gadget...

i had no idea HOW finicky those "phosphors" are to make, and this blew my mind a bit. that's why i subscrubed! having experimented with phosphorescent pigments, to make an exotic display, was gonna mention "LIT" in particular. AFAIK it's by FAR the brightest you can get! (charging a thickly coated 10cm panel for 2 minutes under UV-C was enough to light a pitch dark room for a few minutes. and if there's some charge left, it can even be triggered by a bit of heat. and even heating it to a bright red glow did now harm the luminocity. good shit!) but it fades quickly (which was ideal for my application), where others, i dont remember the name of, maintain a dim but well visible glow fur upwards of 12 hours. those are commonly used in emergency exit signs. PS: EL wire and sheets were super cool, but they're getting outdated, overtaken by LEDs with good light diffusors, like "side emitting optic fiber". comparably pretty dimm and expensive, locked to one color, and also hard to drive, emitting a whining noise, and having pretty limited lifespan and poor mechanical robustness. it was a cool tech, but modern RGB LEDs and lightspreaders just reighn surpreme.

@petevenuti7355 Жыл бұрын
You said that it glows brightly under a UV lamp, as well as a strong afterglow. Even things that are normally defined as fluorescent and not phosphorescent have a decay time, in other words, everything that glows will continue to glow after the stimulus radiation is turned off! It could be for picoseconds , tens of seconds or hours! Personally I distinguish the two by whether or not it involves a quantum forbidden state to delay the electrons jumping down releasing a photon. Without that forbidden state it takes a small fraction of a second to reemit light. Orders of magnitude longer with the forbidden state. Now what the actual official definition is based on, (time or quantum mechanical effects) I am uncertain, it maybe distinguished purely by convention and culture, and yes possibly different in different languages. Some may decide to call all light emitted after a delay phosphorescence, or call all light emitted up to a second later part of fluorescence, I heard it every way in-between! What is THE proper definition?

That's not how it should be done. Pure strontium aluminate has a needle-like shape, while strontium aluminate based pigments are sintered with boron, creating spherical particles.

Stick with commercial products which have far better performance and are less of an inhalation hazard.
