Abstract

Fabrication of organic electro luminescence device using wet process is required in the view point of the process simplification and the reduction of the production cost. In this study, several ruthenium complex monomers were synthesized. Their energy band gaps were measured by using photo-acoustic spectroscopy and the luminescence spectra were measured by photoluminescence spectroscopy. It was found that the peak wavelength can be control from 630nm to 720nm by adding the functional group to the ruthenium complex monomer. It was also found that by adding polyethylene oxide and LiCF3SO4 and sodium hydroxide into the ruthenium complex, the light intensity of the organic light emitting device was increased from 1500cd/m2 to 2000cd/m2 and the response delay which is the characteristic of the electro chemical luminescence is drastically improved.
