Electroluminescence Properties of Dye-Dispersed Poly-Imide Multilayer Light Emitting Diode (Led): (I) Absorption, Photoluminescence, and Structures

Abstract
In this article, the absorption and photoluminescence spectra of Alq3/ poly(ether imide)(PEI) blend films are discussed, in order to get insights on the electroluminescence properties of the Alq3-dispersed PEI multilayer LED. The structure of the Alq3-dispersed PEI films was also investigated by optical microscopy with image processor.
