I'd highly recommend going to Sterling Hill Mine https://www.sterlinghillminingmuseum.org/ and Franklin Mineral Museum https://www.franklinmineralmuseum.org/. They both allow collection of fluorescent minerals from the mine dumps on certain days. If you go to the Natural History Museum in NYC you can see some very impressive fluorescent minerals sourced from these two locations. Also the mine tour is worth it, if nothing else.

Very cool photos, nice to see rocks from a perspective I'd not seen before.

I came across this recently - https://en.wikipedia.org/wiki/Thermoluminescence where it sounds like some rocks emit light upon heating.

Wouldn't a mono camera and filter wheel be ideal setup for this sort of purpose? Assuming you are interested more in the mineralogy than pretty pictures.

If you're into this, you might enjoy the Opal Hunters show on Max.
