Charge Injection, Transport, Recombination and Generation of Neutral Excitations in Multilayer-Dye Electroluminescent Diodes

Abstract
Emission characteristics of multilayer-dye electroluminescent diodes were discussed in terms of molecular structures of component dyes as well as multilayer device structures. Using the same dyes for dispersed dyes in polymer matrices, single-layer polymer-dispersed dye electro-luminescent diodes were fabricated. The emission characteristics of polymer- dispersed dye diodes were discussed in relation with those of multilayer-dye diodes.
