Alq3-based organic light-emitting diodes were studied in terms of electroluminescent spectra and light intensities as a function of the thickness of the light-emitting layer. At approximately 600 angstroms, maximum light intensity occurs and a minimum occurs at 1400 angstroms. The electroluminescent spectra also varied with the thickness of the light emitting layer.
