The present work focuses on the investigation of two types of new materials, phosphorescent and near-infrared, for the fabrication of solution-processible Organic Light-Emitting Diodes (OLEDs). After the introduction of the theoretical background in the first part, the second part concentrates on phosphorescent OLEDs based on copper transition metal complexes. The photophysical properties of.
PDF - Accepted Version 15Mb: Abstract. A range of new materials for organic light emitting diodes (OLEDs) synthesised in the Department of Chemistry at Durham University have been characterised and electroluminescent devices containing these materials have been optimised. High triplet oxadiazole based electron transport materials were tested in devices blended with the host material poly(9.Organic light emitting diodes (OLEDs) are being commercialized in display applications, and will be potentially in lighting applications in the near future. This thesis is about the design of high performance OLEDs, which includes both the electrical and optical design of OLEDs. In particular, the following work is included in this thesis: i) Energy level alignment and charge injection at.Polymer Light-Emitting Diodes Herman Theunis Nicolai.

This thesis investigates the use of the large-area, roll-to-roll compatible deposition technique of ultrasonic spray coating for the fabrication of polymeric organic light-emitting diodes (OLEDs). Firstly, in Chapter 4 a range of different materials are investigated as potential solution processable electron-injection layers, typically this layer is deposited via thermal evaporation in OLEDs.

Abstract An organic light emitting diode (OLED) could be a light emitting diode (LED) during which the emissive electroluminescent layer could be a film of organic that emits light in response to an electrical current. This layer of organic semiconductor is set between 2 electrodes a minimum of one among these electrodes is clear. OLEDs square measure wants to produce digital displays in.

This thesis is focused on the study of the physics and the engineering of organic light-emitting diodes that will aid in the realization of efficient organic polariton LEDs. The main body of work examines various organic semiconductor materials in their ability to reach the strong light and matter interaction regime and, subsequently, to be used in OLEDs as the emissive component. Furthermore.
Exciton Management in Organic Light Emitting Diodes Carmen Nguyen Doctor of Philosophy Department of Materials Science and Engineering University of Toronto 2019 Abstract Over the last few decades, there has been great interest in the further development of OLEDs for practical applications. They are currently commercially-viable for low-brightness applications, such as in displays for mobile.

A Thesis Submitted to the Department of Center for Materials Science and Engineering in Partial Fulfillment of the Requirements for the Degree of Master of Science in Materials Science and Engineering. ABSTRACT. Organic Light Emitting Diodes (OLEDs) based on the principle of electroluminescence, constitute a new and exciting emissive display technology for flat panel displays. In order to.
In this thesis we have investigated GQDs for an emissive layer in all-solution-processed organic light emitting diodes (OLEDs). Our GQD-based OLEDs are designed and fabricated as two different structures: bottom emission configuration on ITO substrate and top emission configuration on p-Si substrate. For both structures, GQDs show multiple.
In this paper, the vapor-deposited and solution-processed organic light-emitting diode (OLED) technology development paradigms are described and then compared with respect to their prospects for enabling general lighting applications. Two key development needs are improved device efficiency and lower cost fabrication methods. Progress in these areas for solution-processed OLEDs is illustrated.
