    Can anyone please tell me how can I make a fine invisible UV-glowing powder?

    My searches came up with nothing so I thought I'd ask here...

    Thanks in advance.,


    Good Brother

    What do you mean by invisible? It's still a white powder under normal light.

    Well synthetically modified sugar and Quinine come to mind...... you'll have to remove the water from the later though....

    If that doesn't work then either way... in general your powder will have to be a chromophore and made up of material that does not absorb in the visible light spectrum...

    SciFinder and a UV-vis table should help you with this... but I would guess that something suitable for your needs has already been made before so do a quick SciFinder search and you'll likely find something...

    hope this helps.
    Good luck. : )

    won't adding water to the powder make it a liquid UV-glowing substance?

    Not necessarily. Sufficient liquid may be able to 'fill in' the crystalline lattice of certain substances.

    As far as water soluble fluorescent compounds go, Hanuka is correct. Check quantum dots, they're pretty cool and fluoresce very bright green.

    Hello,
    here is a link on crystal lattice structures which I think is a good introduction: http://wb.chem.lsu.edu/htdocs/people...e/01intro.html

    of course none of this will really matter in relation to your original questions as the simplest way to find a solid - like the one you are seeking - is to look one up on SciFinder and if you must - make your own - based on the parameters that best describe your situation....

    In this case you want to make a 1.) clear 2.) solid 3.)Chromophore....
    Well synthesizing the latter in the lab really isn't overly difficult.. so as long as the material you start with is clear... and solid.. and you are careful about the synthetic modifications that you make in the lab then arriving at the material you desire shouldn't be that difficult...

    hope this helps..
    Good luck.

    Is there such a thing as a transparent powder? Pure glass, ice, sugar, salt, diamond, any transparent solid becomes white when it's powdered.

    Is there any water soluable additive which stores energy from sunlight? Imagine mixing water and the glow substance in a 2 liter bottle and leaving it out in the sun and it would glow once the sun went down. I see some expensive additives for things like oil based paint. But nothing that could be mixed with water. Preferably translucent onc mixed. I'm working on a project in west Africa to install clear bottles in tin roofs with water inside. Sun passes through the top on the roof side and comes out underneath into the room. How great would it be if it could be storing energy all day and offer some light at night too.Is this possible? I have no education in Chem other than vinegar and water in a volcano with a Lego man glued to the side.

    But I don't like the taste of detergent.
