After dragging my heels for some time, I've finally gotten around to taking some photos of UV induced phosphorescence, as promised in this thread: https://www.ultravio...high-speed-uvf/ . The setup is basically the same as in the other thread, just with phosphorescing dye instead of fluorescing one. So far I've only used green dye, just to see how things turn out.

Please note that the photos are almost straight-out-of-camera, mostly just cropping and a bit of editing done; I haven't bothered to edit out the uninteresting drops yet. But even if these shapes bear some resemblence to the fluorescence photos, the main difference is that here the traces of the flying droplets are properly smeared out because of the duration of the light-effect and also the columns are smeared out in some of the photos.

The 2nd-to-last photo shows such an intricate shape. Almost looks like a temporary cup formed and then liquid spilled from it.

I think the "ghosting" effect from the phosphorescence is quite interesting.

I also like that one. These photos are basically the first ones I took, and I hope to take more photos of ghosts on the next weeks.

As you can see, it's also possible to take photos of some elementary particles colliding. Clearly, the red particle is a proton and the blue particle is some other -tron, and after the initial snapshot before the collision we can observe a multitude of subatomic particles created by this event, probably quarks and gluons, zipping away in all kinds of directions. It's like a mini-LHC :lol:

You need more energy to create some fun particles. The recent photon merger to create a boson is interesting.

That a side, your images are very captivating.

A few more recent ones, this time also some in red.

Thanks :smile:

Here are a few "proper" ghost-photos. I turned off the flash and only kept the LED which was pointed at the basin. So the light is coming from the energy stored in the basin and is therefore much fainter.
