Electrical conductivity and luminescence of metal-organic nanocomposites

Journal of Russian Laser Research Aims and scope

Abstract

We presented the results of experimental study of electrical and luminescence properties of planar nanocomposites based on gold island films and layers of efficient organic luminophores — aluminum (III) 8-hydroxyquinolinate (Alq3) and europium β-diketonates [Eu(DBM)3 bath, Eu(DBM)3 phen, and Eu(DBM)3]. The mechanisms of electroluminescence of such hybrid systems are discussed and the processes of luminescence excitation in the organic component of nanocomposites are considered in detail. It is shown that the spectral characteristics of europium β-diketonates are controlled by the Eu3+ ion fluorescence. The proposed mechanisms of nanocomposite electroluminescence are confirmed by the results of measurements of cathodoluminescence spectra of organic luminophores.
