Organic electroluminescent devices (OEDs) emit light when an electric current is applied to
a thin film section. They arise from two main technology branches—small molecules and …

The aim of this chapter is to give an in-depth analysis of transition metal complexes that
areuseful in conversion of solar energy into electricity, and in organic light emitting diodes. In …

A new series of iridium (III) mixed ligand complexes TBA [Ir (ppy) 2 (CN) 2](1), TBA [Ir (ppy) 2
(NCS) 2](2), TBA [Ir (ppy) 2 (NCO) 2](3), and [Ir (ppy) 2 (acac)](4)(ppy= 2-phenylpyridine; …

All-polymer RC filter circuits by all-inkjet printing technology are fabricated for the first time.
Conductive polymers such as polyaniline and poly (3, 4-ethylenedioxythiophene) have been …

Hole mobility in N, N′-diphenyl-N, N′-bis (1-naphtylphenyl)-1, 1′-biphenyl-4, 4′-
diamine (α-NPD) is evaluated by electrical characterization in the ac regime. The frequency …

The internal electric field in multilayer organic light-emitting diodes (OLEDs) is investigated
using a combination of experimental measurement and numerical device modeling. This …

New benzothiadiazole-based materials containing methyl substitution are prepared and
characterized as promising green/yellowish green emitters for electroluminescent …

In this letter, the authors had quantitatively investigated the recombination zone in the mixed-
host (MH) emitting layer (EML) of an organic light-emitting device with different mixed ratios …

By using pyran‐containing donor–acceptor dyes as do** molecules in organic light‐
emitting devices (OLEDs), we scrutinize the effects of charge trap** and polarization …

We present a closed description of the charge-carrier injection process from a conductor into
an insulator. Common injection models are based on single electron descriptions, being …
