Abstract

This revised thesis has been submitted in 2021 due to findings of academic misconduct in the original thesis. The misconduct included improper citation and plagiarism of Dr. Khadir’s PhD thesis [1], particularly in the introduction, the state of the art and images 1.1-1.6, 2.4, 3.2, 3.4.

The localized surface plasmon resonance (LSPR) is known as a phenomenon that allow to enhance the efficiency of Organic Light Emitting Diodes (OLED). This work researches the dependence of OLED performance with and without metallic nanoparticle incorporated in the organic layers. Diodes with periodic (PMN) and random (RMN) metallic nanoparticles along with both types of nanoparticles were compared to the reference OLED. Thermal evaporation technique was used to form organic layer under high vacuum and e-beam lithography to compose periodic metallic structures on nano scale. Reporting that periodic structure increases the luminescence and electrical properties of the device for approximately 20% but devices with both types of nanostructures demonstrated 50% decrease of efficiency.
