Abstract

The first part of this thesis focuses on the design and testing of an organic light emitting device (OLED) with a three dimensional geometry. 3D metal / polymer bulk junctions were grown inside the pores of nanoporous gold (NPG) by using electrochemical deposition and electrochemical polymerization. Junctions contain- ing zinc oxide, polyaniline and poly(3,4-ethylenedioxy-thiophene) were evaluated by comparing light emission, current-voltage (I-V) characteristics, surface roughness and UV/Vis spectra. 2D and semi-3D devices were tested and results are compared to a conventionally prepared 2D reference device. In order to complete the transi- tion from 2D to 3D OLED’s, future work is required to find a suitable emission layer for the 3D device. The second part of this research thesis deals with the synthesis of silver nanoparticles. These particles were grown using electrochemical deposition and polyol synthesis. The particles morphology is studied at different angles with a scanning electron microscope (SEM). These pictures are used to calibrate a novel 3D digital image correlation algorithm.
