1. An electroluminescent device comprising:

  • a. a thin body of light-generating, aromatic, electrically nonconducting, hydrocarbon material, b. a first solid phase electrode having an electrically conducting surface contacting a first surface of said light-generating material, c. a second solid phase electrode contacting a second surface of said light-generating material, said second electrode containing negative ions of an aromatic hydrocarbon material capable of injecting electrons into said second surface upon the application of a negative potential to said second electrode relative to a potential applied to said electrically conducting surface of the first electrode, and d. at least one of said electrodes being transparent for the transmission therethrough of light generated in said light-generating material by recombination of said injected electrons with holes.
