CHARACTERIZATION AND LUMINESCENCE PROPERTIES OF THE DYE-DOPED POLYMER LANGMUIR-BLODGETT FILMS*

Received Date: 20 April 1998

1, 1,4,4-Tetraphenyl-1,3-butadiene (TPB) was successfully introduced into the polymer multilayerfilms by means of Langmuir-Blodgett (LB) technique. Results of UV-VIS spectra and X-ray diffractionshowed that the uniform films had a layer structure similar to the superlattice of organic multiple quantumwells. The electroluminescence (EL) devices fabricated from the doped polymer LB films emitted blue light.Compared with the casting films, the photoluminescence (PL) and EL spectra showed that the exciton energy shifts to higher and the half-width of the emission peak becomes narrower due to exciton eoncinement effect.
