405nm Fluorescent Material Wanted

[TheLengthWaiver]

Hi All

Apologies if this is in the wrong section.

I am looking for a material that will fluoresce under excitation under a blue 405nm LED.
Preferably it would be clear to begin with and fluoresce orange under excitation, I have considered Quinine from tonic water, however this fluoresces blue and when concentrated appears orange.

Additional criteria would be that the material would be water soluble and non-toxic.
Thanks!

Hi TheLengthWaiver! Welcome to BLF! I don’t know of a material like that, but doing a ’net search comes up with UV glowing materials, not blue or violet glowing materials. Still, you might get a little bit of glow from those. Here’s a site dedicated to glowing things. Maybe they can help you. UV Reactive Colored Powder | GLO Effex

By the way, what are you making with this material? Sounds very interesting!

Hey, just looking around, I found this interesting bit at a site called glowinc.com:

The popular stage lighting company, Chauvet, released a “black light” consisting of 192 “UV” LEDs. This product is a great VIOLET light using 405 nm, visible light, violet LED’s. However, it is almost completely useless as a black light. You can understand their reasoning when several DJ’s reviewed this light as much ‘brighter’ than more powerful fixtures emitting true long wave ultraviolet light. The reviewers were making this determination by how much light they could see. Properly, they should have used fluorescent paint to determine the best fixture.

Brilliant, thank you David, both sites have been really helpful.
By the looks of things their formulas are adaptable- I just hope they’ll still fluoresce sufficiently within the visible spectra we’re working in.

I’ll update when I know a little more!
Thanks again.

UV LED’s have been a popular topic around here for a few months. So, it would be good if you’d let us know what kind(s) of “glowing” material(s) can be affected by 405nm light, which is actually visible violet rather than true UV. I also saw that glow-in-the-dark materials can be charged fairly well by 405nm light, but that’s not the same as fluorescent material.

Why are you trying to use 405nm instead of true UV light anyway? Is it just because that’s what you have (or can get cheaply)? Or is it because of safety concerns? Or something else? I’m curious! :innocent:
