Is there any way to make diamond flouresce in the visible or near IR region?

Here is article by GIA (Gem Institute of America) it is UV activated.

This is a great place to start.
I was looking at absorption bands and multiples – unsuccessfully.
I wonder what wavelength works best . 254nm? 302nm? 356nm?

Thanks!

To be exact you might have to look up the absorptance of the possible contaminants. As a first guess, I would try the shortest wavelength because it would have the highest energy. Fluorescence just needs electrons kicked up. More energy = more kick. The fall is where the characteristic wavelength gets emitted.

Ideally, I’d like this to be as simple as hitting it with something like UVC 254nm and filtering the receiver for 508 nm. (or 302nm in, 604nm out; or 356 in, 712 out). Unfortunately I do know the contaminants. They will be the key.

A literature study of “pure” carbon diamond did not show any unique absorption bands in a useful area.

The articles talk about fluorite, calcium, or boron contaminants being the cause. Probably have to look up their fluorescence characteristics.

Unfortunately the internal contaminants are unknown or nonexistent. And there can be many unrelated contaminates in the area. I’d like something that worked off the carbon bods in the diamond lattice.

I had never heard of carbon fluorescing, but here it is:

Now we’re getting somewhere.
Hmm…. I wonder if I can i bombard the mix with microwaves and get something repeatable out.

I want something like the red light seen in this enjoyable video. Wire Cutters
