Looking for help

[Guest just stoppin]

Hello all, I was hoping someone could help me with a question, Is there a powder or oil that you can only see when wearing glasses, somthing that will show if you put it on clothes or in there hair, you can't see it with the naked eye, like when playing paintball at night, you can see were that person is in the dark, Somthing like a Luminous Meterial, I hope i'm explaing it the right way, I have been doing a search and have come up with nothing so far, Thanks All

you want something which you can not see without without special glasses?

 

or you mean in a special condition?

 

you can see counter-forge markings on passports with UV (ultra violet) light.

 

im not sure exactly what you are looking for.

yeah, oxidize oxalic phthalate ester with hydrogen peroxide. it will form phenol and carbon dioxide but the cyclic intermediate (1,2-dioxetane-3,4-dione) is formed and luminesces. as well, you could use zinc sulfide or a nice powder mixture of Al2O3, SrO and Eu2O3 for a green colour or Al2O3, SrO and Dy2O3 for a blue colour
