Strange fluorescent phenomenon

[Arayan]

Today I tried to enlighten my mineral collection (more than 100 pieces) with a blue-ray laser (405 nm) and a mineral called fuchsite showed a strange phenomenon, it start glowing for a few seconds only in some located points of the rock. If I have time in the future I will try to investigate the phenomenon :thinking::thinking:

That is pretty cool! Natural glow-in-the-dark, just scrape some off and glue it to some paper.
I'v always been a rock hound, would love to see a bit more of your collection.

What you got happening there is simular to something I noticed with a few of my samples of Fluorescent minerals. Notably, (correction: Flourite CaF2) There is a phenomena known as delayed fluorescence or after fluorescence. Your sample is the longest delay I have seen so far. Interesting. Are you able to get a closeup of the glowing area? I am very curious!!

FYI, Fuchsite also quite commonly contains red ruby. I can see from your picture that you do indeed have ruby in your sample.

AWESOME!!

:thanks:

would love to see a bit more of your collection.

Thanks I'll post them in "off topic" section

thanks, I didn't know this phenomenon ...have you posted your minerals on the forum?

yes, I have a video of the Willemite exhibiting (briefly) an orange after fluorescence.
CORRECTION : Sorry, actually it was Flourite that had the delayed fluorescence. CaF2. pink under UV and 405nm.
Willemite does glow bright orange/yellow.

Pretty cool ! I can say ! I love fluorescent phenomenons!

I love these fluorescence effects...can't wait to get my hands on an 405nm laser
Thanks for posting your finding!
