Electroluminescence, photoluminescence and electroabsorption of a lightly substituted anthracene langmuir film

Abstract Optical data are presented for a novel thin film structure based on anthracene. Thin films of the 9-butyl–10-anthryl propionic acid derivative were prepared using the Langmuir-Blodgett technique. By applying electric fields in excess of 10 6 V cm −1 both electroabsorption and electroluminescence results have been obtained. The electroluminescence spectrum exhibits a shoulder at the wavelength where the maximum in the fluorescence spectrum occurs.
