Yk. Kim et al., ELECTROLUMINESCENCE PROPERTIES OF DYE-DISPERSED POLYIMIDE MULTILAYER LIGHT-EMITTING DIODE (LED) .1. ABSORPTION, PHOTOLUMINESCENCE, AND STRUCTURES, Molecular crystals and liquid crystals science and technology. Section A, Molecular crystals and liquid crystals, 280, 1996, pp. 343-348
In this article, the absorption and photoluminescence spectra of Alq3/
poly(ether imide)(PEI) blend films are discussed, in order to get insi
ghts on the electroluminescence properties of the Alq3-dispersed PEI m
ultilayer LED. The structure of the Alq3-dispersed PEI films was also
investigated by optical microscopy with image processor.
