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.
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-vinylcarbazole) (PVK).
The Electrical and Mechanical Study of the Flexible Organic Light Emitting Diodes Chien-Jung Chiang A thesis submitted to the Faculty of Science, The University of Durham, for the degree of Doctor of Philosophy Organic Electroactive Materials Group Department of Physics University of Durham January 2011. 3 Declaration All material contained in this thesis is original and is the result of my.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.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.
Indeed, most applications of organic light-emitting diodes are related to visible light emission (e.g. illumination, signs and displays). That is the reason why the optical characteristics of OLEDs are usually given and compared in photometric units (not radiometric). Photometry is essentially radiometry normalised to the spectral response of.
