High Voltage makes plastic Fluoresce ?
Ғылым және технология
After experimenting with discharging a capacitor, I noticed that the plastic insulation on crimp terminals fluoresces after being struck by the radiation from the spark.
I've never encountered this effect before and I do not know what is causing it.
I first thought it was a fluorescent plastic and was reacting to the intense UV light emitted by the spark, but under direct UV light the plastic does nothing. I cannot externally replicate the conditions which cause this phenomenon.
If you know why this might be happening, I'd very much like to learn about it. Please let me know!

The plastic might not be visibly fluorescent under a UV lamp, but those sparks are probably put off very high energy UV which is being blasted, point blank, into that plastic. So, under those conditions, I believe it is possible for something originally materials thought to be non-fluorescent are likely to fluoresce.

I think the plastic has a triboluminescence property. can you try to highlight the plastic with a 405nm laser?
That's a really cool sound.
I suppose it is phosphorescence which is caused by the blue and ultraviolet photons emitted from the spark.
Well. I think it's still to early to rule out UV as the source. The distribution pattern looks most certainly matches how a light source is shining from the side and casting shadows. Intensity might be the key. If your UV light source is just not comparable with the amount emits by the spark. You could try put some samples of the same material near the spark but not contacting any electrified component to rule out direct heating or electricity. See if it still reproduces the results.

Yes that's true , like nuclear shadowing
I think the ark generated UV radiation and this plastic was probably recycled from other plastic materials and there was some plastic in it that did contain phosphor.

Most logical explanation so far
@DanTheAwesomeMan: simple, the high voltage causes a luminescent reaction in the chemicals of which said plastic is composed of, the plastic may consist of some electroluminescent chemicals and some resistant semiconductors, you may want to research what chemicals the plastic is made of and check further into it if you are super curious,
I think it's deep uv from the corona of the arc making the plastic fluoresces, search this in youtube "Corona Power Line Inspections by PDG Helicopters"

The plastic has UV glow coating to identification in dark or low light conditions..your sparking creates UV which makes the plastic glow
5 years later and eardrums are still getting popped
u nuked it with radio activeness or u just invented a flux capacitor

Could be phosphorescence but less than youd expect, normally unnoticeable. But a spark like that radiates a huge amount of UV and that might be what's causing the glow.

Masai Uruhara Oh, it was just a joke.
Are you using the diode out of interest? Could you ve forcing a crude led perhaps from the intense voltage causing a breakddown in some way? Im vwry interested also now
A possible thought, modern photosensors (in your camera) are sensitive to IR, could the afterglow be heat related? Just brainstorming hopefully without being struck by lightning
This is a shot in the dark but perhaps the capacitor is charged enough to create a corona discharge after the main arc?
Cool !!
Hey, my headset is glowing too. 👍
Intriguing.
That depends, did you take them off of florescent tubes?
A blue LED will cause certain plastics to fluoresce. Maybe an abundance of energy at 440 maintained fluorescence that gradually dissipated with the charge.

The energy was bouncing around in the polymer. Interesting.
Quite peculiar, looks cool though. Also never seen something like this yet.
if you got a strong enough 405nm laser it can make some plastic glow also. I found out about it, I'm thinking maybe 2 years ago with the kitchen socket cover.

Those are actually made to slightly glow in the dark you idiot. And from that I've learned you have old sockets
Given that you mentioned trying to illuminate the plastic with UV but didn't get a result.. I would wager that the spark gap UV intensity (and wavelengths) are strong enough to penetrate quite deep into the plastic. There may have been some UV fluorescent in the plastic but for whatever reason is no longer active in the outer layers. You could test this by cutting a piece of the plastic and exposing the fresh inside to UV. As others have said, it is definitely exited electrons releasing photons on returning to their ground state. It's further possible that the excited state is simply so high as not to be noticeable from any reasonably obtained UV source, and the extreme energy level itself is needed to excite the electrons enough, so that when they release their photons from within the plastic they do so in the visible spectrum.

I doubt it would penetrate the plastic as it's breakdown would be in megavolt per mm range and hf high voltage tends to travel on the skin of a conductor rather than penetrate it .
It looks like a simple heat flash point transfer glow (in other words heating the material up to flash point for a few Milli seconds not long enough for it to combust but enough that the residual heat gives a glow)
if you got a strong enough 405nm laser it can make some plastic glow also.
Could still be UV, but a shorter wavelength / more energetic part of the spectrum..
*Well, the manufacturer would be some important information to be presented with!*
the volume warning help me a lot. I left the sound because I thaught it was a troll and you whuld do it at a low Hz
That's cool
Thanks for changing my earphones to hear aids.
perhaps you will find this reading enlightening "Plastics emit fluorescent light when exposed to a brief flash of light, and the emission decays with time in a distinctive pattern " Read more: www.theengineer.co.uk/manufacturing/news/new-process-simplifies-recycling-of-plastics/1019102.article#ixzz3B8OMdFti

+DanTheAwesomeMan Great video! Very thought provoking. What you might be seeing here is phosphorescence which is same process as fluorescence but causes a delayed effect. The physics of fluorescence is to do with energy states in atoms. These states come in discrete energy packets of E=hv where h is a universal constant (planks constant) and v is the frequency of the incident light. The light produced in your spark is equivalent to millions of photons (the larger the spark the more of them) many of them carrying this fixed energy amount of hv. What is happening in the plastic, is those hv photons of light from the spark that reach the plastic, cause a similar number of electrons in the atoms of the plastic to move to a different energy level (the energy gap being hv). All these electrons then drop back to their original position and in the process re-emit the energy at a different frequency v (i.e. Its a lower frequency because some of the energy will have been lost due to collisions in the material). So what your seeing is the consequence of many of these 'excited' electrons re-emitting light whilst moving back to their original stable state. Now, that particular plastic material might hold onto the energy for a longer time, before the electrons return to their original states. This effect is called phosphorescence. The details are a lot more involved and need a bit of quantum theory, but this (I believe) is the general essence of what is happening.

maybe the plastic is coated with some fluorescent paint. Try put a UV light next to it and see if this glow happen again.
Wooooow
I witnessed this phenomenon as well!! I shorted the two leads of a 250v capacitor bank that I made over a sheet of paper and it glowed a little!! No idea why though
UV fluorescence?

Maybe it's something like the OLED's working principle...
it might be that the UV from the spark excites the plastic. Try shining a UV led at it.

The discharge produces some intense ultraviolet radiation, which excites the plastic and makes it glow, in the same fashion as in glow in the dark stuff, that you put near a light, and it glows for a while afterwards. The plastic must have some phosphorescent substance in it.
To much POWER
Damn my ears are bleeding and scared the crap out my dog.. pretty cool though. 👍 the glow is due to the amount of Uv radiation being produced in close proximity. Damn good way to get a tan 🤣😁
It could be electrical radiation from the electrical pulse that is trapped in the material causing it to Glow.
Damn! Mute the audio!

it is most likely the result of the capacitor discharging.
i could guess the move of electricity through that plastic emits photons
