List all known UV fluorescent material

My fat TV after I hit it with 405nm it glows very faint for about a second, sort of like GiD paper but way less noticeable. It is only noticeable in pitch dark areas. Of coarse I only use 5mW blu rays for this because higher powered ones might destroy my TV lol
 





I finally got around to trying this Manuel. So instead of a 405nm laser, I defocused my >1 W 445nm laser and with yellow glasses pointed it on a houseplant. Everywhere there was a lot of green chlorophyll, I saw bright red fluorescence. I highly recommend this because the effect is dramatic. Bright red houseplant LOL. ;-)

Krutz - remember to use your uv-blocking yellow glasses when watching for fluorescence. not only to protect your eyes - its a whole different world. shining a blu-ray at green plant material, its boring. but with glasses, chlorophyll shines red, you can clearly see what parts have how much chlorophyll, its really fascinating (although its hard to describe).

raw coffee beans! ( i roast my own coffee so lots of raw beans around )
 
Can someone de-focus a 405nm and shine it on a group of diamonds, please and post a picture? Roughs if you have access. I don't have a 405 yet, but have a massive UV LED flashlight that makes diamonds glow blue. I would like to see a comparison. About 1/3 of all diamonds will glow under UV. All diamonds glow under XRAY =P
Thanks, Jeff

You're never going to list all the chemicals on a forum! Too many to count

Uranium compounds (Uranyl phosphates)
( Uranium glass / vaseline glass)
Sodium Iodide
Semi-opal
Zinc Sulphide (ZnS) VERY BRIGHT!!
Tonic water - Quinine
Highlighter ink (esp - yellow) It's got Sodium Flourecine in it.

I tried potassium iodide and got nothing.
 
Highlighter colors I tried to fluoresce with my Arctic:

yellow
orange
green
pink
blue


Only the blue fluoresced, it was a deep orange, nearly red.
 
I recently re-stained the wooden doors in my apartment, when i shine my 405 on it the dot actually looks white. pretty cool effect. makes it look like its a white laser.
 
EL paint from the Luxprint kits (fluoresces greeny blue under 405)

White EL paint from same kits.

Those orange Highlighters

Carbon Fiber (at least my carbon fiber wedding ring, as well as the carbon body parts on my sport bike) :D
 
So ar the brightest thing i have found is orange airsoft bb's. Pretty much any neon orange colored plastic will be extremely bright.
 
All gin and tonics, but AFAIK only Tangeray gin does straight, however the only other gins I have only tried where cheaper brands so others may do the same.

Back in the 80's( the high point in my clubbing days) you could buy IIRC Murine AC eye drops that made your eye glow yellow/green under UV.
For freasons I do not know they changed the formula and that was the end of that. {plz dont ask me why I needed eyedrops back then}


Eye doctors have tiny slips of paper -size of litmus strips, they touch the strip in the corner of your eye and view them with all except UV turned out.

My Dr. gave me a few and at a halloween party that had about 30 blacklights a few of us really wierded out many of the partygoers. I went up to some of my friends with my sunglasses on and asked them to look close to see if I had gotten something in my eye while standing very near two 40 watt 48" BLs, most quickly just got away from me as quick as they could when , up close, I lifted my glasses up.

. These can be purchased on-line afaik by anyone but you must buy a lot of them. IIRC the smallest I saw was a container of 100.
