Galvanoluminescence
Encyclopedia
Galvanoluminescence Is the emission of light produced by the passage of an electrical current through an appropriate electrolyte
in which an electrode
, made of certain metals such as aluminium
or tantalum
, has been immersed. An example being the electrolysis
of sodium bromide
(NaBr).
Electrolyte
In chemistry, an electrolyte is any substance containing free ions that make the substance electrically conductive. The most typical electrolyte is an ionic solution, but molten electrolytes and solid electrolytes are also possible....

Aluminium
Aluminium or aluminum is a silvery white member of the boron group of chemical elements. It has the symbol Al, and its atomic number is 13. It is not soluble in water under normal circumstances....
or tantalum
Tantalum
Tantalum is a chemical element with the symbol Ta and atomic number 73. Previously known as tantalium, the name comes from Tantalus, a character in Greek mythology. Tantalum is a rare, hard, blue-gray, lustrous transition metal that is highly corrosion resistant. It is part of the refractory...
