Video showing (longwave) Fluorescent minerals reacting to Bluray

I decided to make a video showing Fluorescent minerals under normal (ambient) lighting then exposing them to a ~350mW bluray laser. Clearly you can see that there is a definitive difference between normal lighting vs 405nm.

In my collection is SemiOpal (Green in 405), (Willmenite Orange), (Calcite Pink/red), Flourite (pink), (Wallastonite)- whitish fluorescence. In the back was piece of Scheelite. It didn't fluoresce as it needs shortwave UV to do start fluorescing.
If you look carefully at the end of the video you'll see that the Fluorite is still glowing after the laser is off. REALLY LOOK carefully. This is what is known as delayed fluorescence or phosphorescence.


Enjoy.

Wow, nice video!

I have also been experimenting with such materials.

+Rep for awesomeness!

The surprise came with Fluorite which continued to emit light a few milliseconds after the blue ray was turned off. Really, interesting effect. Another material that seems to really like to exhibit delayed fluorescence is Sodium Flourescine.
I wasn't expecting the delay to be so long with CaF2... hmm I better investigate this further.

That is why i love 405 + rep

Very interesting...
405nm will for sure be my next laser!
+rep for this nice video

Very nice...we had the same idea... +1 Rep
