Abstract: The photoluminescence and electroluminescence properties of plasma polymerized naphthalene films are investigated.The emission is a fluorescence rather than a phosphorescence process with a life time in the order of a few nanoseconds.Blue emission with peak wavelength 490 nm from the Al/PPN/ITOdiodes was observed when operated in a continuous DCmode for a forward bias ITOat positive polarity.
