Nice, that chart’s helpful for me to visualise. Very interesting.
What does it mean though when you say:
?
Nutshell
Phosphor is good at turning energy into light
Inside of a Tritium vial (or fluorescent bulb or various other stuff) is coated with phosphor
Radiation hits phosphor, phosphor emits light
More energy doesn’t necessarily make more light, the phosphor can only do so much
I guess a shitty analogy would be, an led doesn’t care how many amps you feed it, it will only use what it can
Also kinda the nutshell idea with how night vision tubes work
A image intensifier tube inside the unit uses phosphor and feeds it energy uses it it act like a multiplier for any light coming in
(This is why night vision is typically green, tho the cooler things are using white phosphorus now a days)
Also used in old school CRT tvs
Back of the tv shoots electrons at the screen, and hits phosphor, which turns the electron bullets into light on that pixel

That makes sense. In order to take full advantage of more tritium, you would in turn require more phosphor to emit more light.
Neat. Didn’t know that’s how nightvision tubes worked. Neat. But with those, my understanding is that more light actually damages them, at least with older models, Idk about the newer gen stuff.
They must need to be very cautious with the ones using white phosphorus given how dangerously reactive it is to water. Bet the manufacturing process is extremely strict.
Thank you for explaining that to me. Always nice to learn new things, and deepen understanding of existing knowledge.
Playing the Black Mesa remake for the moment

Thanks 
And additional special thanks to you and @mrln for trying this out first - it was to a big part your first hand experience that made me decide it’s worth a try

I wonder if aqua glow powder would glow for longer. I think the green powder is brighter initially, but the aqua becomes brighter if you wait an hour.
@Coma
Been a bit, how’s the diy glow tattoo ink?
Both any further work on the formulation or delivery method
And
How’s it settling in?

Oh, i need to try that!
Yeaaaah, sorry, I’m really lazy currently 
It’s still glowing, and I don’t think it has degraded much - it’s really hard to capture it on camera, but that’s roughly what it looks like now (though with a bit more daylight because the cam was bitchy):
The blue-greenish ink is brighter, but the green one seems to glow longer, at least that’s what it looks like when I poke it with UV light.
Main problem is, my legs don’t get much light during the day, so I can’t tell how much the ink would glow by itself - so today, I decided to try some different placement and poked my fingers. I’m still a bit sad that I suck at tattooing, but I love to be my own little experiment
I used both green and blue-green (is that what you mean with aqua, @asdf?) powder with relatively little liquid (just enough so it wasn’t a paste but a rather thick fluid). Right now, about an hour after tattooing, it looks like it didn’t work at all (there are so many spots with seemingly no pigments), but I know that from my leg already - when it settles, after about 2-3 days, it usually looks better. Though I have to say, poking fingers really sucks a bit, you can’t stretch the skin (unless you have three hands), the skin itself it pretty thin, and it really doesn’t help that I use nearly invisible ink and can hardly work with liners or stencils, so it’s sometimes more of an educated guess where the lines should go 
Really curious to see your results

Are you trying to tattoo with a UV lamp on, or are you just using a “blood trail” to see where you have been?
It sounds like you need to take your SUCCESSFUL experiment to a willing tattoo artist, although, I imagine, that will be the tricky part
interesting… what do you mean? do you just mean that after an hour the aqua has faded less? surely it does not “get brighter”, it simply “is brighter” than other colors that have faded more?
For the finger tattoos, I painted the design with a white pen (because it was more than just a simple line this time), basically rubbed it off again until it was nearly invisible and did the first round of poking. I then removed excess ink and planned to just follow the reddish lines, but to my surprise, they were nearly invisible… either I poked too shallow or skin on fingers is strange in many ways 
But… well, I was impatient, so I took some pictures today - the pigments still have to settle, they will still fade a bit and I have to rework several spots, but here it is:
I’m a bit surprised by myself - I know it’s not even good, technically, but to see it glowing faintly when I wake up at night filled me with so much joy I nearly felt like crying.

Planning a trip to Koln so you can poke my fingers with your fairy UV magic powder!

Haha, I’m happy I slowly start to learn how to poke myself - I don’t think I’d try than on anyone else

Well you’ll need Guinea pigs to improve at some point 
Well im not sure if a Guinea pig is the best choice, the fur obstructs the view on the tattoo work xD

Sorry, totally forgot to answer to that part
Yep, this would be tricky. Anyone who does tattoing as a “real job” would risk losing that job by using unknown (or rather non-allowed) pigments. And that’s a risk few people would be willing to take, and a risk I would not like them to take as well. I still do not know myself if the pigments are okay or if they are dangerous in the long term - I know my body accepts them, I do not get strong reactions (just the usual slight redness that comes with every kind of tattoo) and they seem to last for a while at least. So I’m not surprised that all professionals I asked about this told me to better not do it - I asked for their professional opinion, and that was what I expected to get 
A good friend of mine, though, who does stick and poke tattoos on himself for quite some time (and who provided me with lots of information and tips about all that - thanks my dear! ), saw the pictures today and seems quite interested to do this himself, so I think about trading some of my pigments and get him tattoo my right hand in exchange
I figured that would be the case.
It would be good if they let you sign an indemnity waiver
even though hes not a professional, at least he will be the extra set of hands you need.
For what it’s worth, although they are not technically perfect, they still look amazing

I hate to hijack this awesome thread, but … that powder would look great mixed with 3D printing resin (pico )
