Chemicals that glow with specifics colors when exposed to an current

I'm looking for certain chemicals that glow with specifics colors when exposed to an electric current.

What colors and how will you apply the current?

Look in Electronics, I think they have diodes that do the same thing ;)

What colors and how will you apply the current?

im looking for red green and blue, and as for the current it will most likely be direct current.
and it has to be a chemical.

Do you know of any matter that we interact with that isn't a chemical? Will this chemical be a gas and will you apply current across electrodes separated by this gas? Will it be a solid and will you apply current in the form of an electron stream from an ion gun? Will the substance need to be electrically conductive and exhibit electroluminescence as a solid?

im going to use the chemicals in small glass-like cells.
the electric current will be supplied through wires.
it needs to be electrically conductive when diluted in the glass-like cells.
and it needs to exhibit electroluminescence as solid and liquid.

Look http://patft.uspto.gov/netacgi/nph-...,749,977.PN.&OS=PN/3,749,977&RS=PN/3,749,977" for a description of a solid electroluminescent device. If the phosphor were dispersed in a low dielectric fluid with a high zero shear viscosity (viscoelastic additive) it would work in solution (actually it would be in suspension) as well. Voltages are pretty high in these devices.

ill see if that works.
