Organic Light-Emitting Diodes with Highly Conductive Polymer Electrodes as Anode and Their Stress Tolerance

Abstract

In this conference the generation and uses of high magnetic fields were reviewed. The fields of application ranged from bio-magnetics on the one hand to solid state and nuclear physics on the other. In this report the emphasis is on the methods of generating magnetic fields, both steady and pulsed, and on the latest developments with high critical field superconductors, Steady fields up to 130 k~ have been generated in conventional coils, while in liquid hydrogen-cooled coils fields of about 80 kG have been produced. At the time of the conference the highest field generated in superconducting solenoids was about 69 kG, using niobium-tin. The critical field curves of another material, vanadium-gallium, V,Ga, as far as they have been measured show the possibility of critical fields rising to 500 kG at 1" K.

Solution-Processed Green-Sensitive Organic Photoconductive Device Using Rhodamine 6G

“…Therefore, most of the incident light was absorbed by R6G while irradiating the green light. The larger photocurrent densities were obtained compared to the reference device without the PEDOT:PSS layer when P HC V4 and PH500 were used as the carrier transport layers due to the high conductivity [18,19]. Since work functions of all the PEDOT:PSS layers were almost same, this result indicates the photo-induced carrier efficiently moves to the electrode side.…”

“…At first, several kinds of poly (3,4-ethylenedioxythiophene):poly(styrenesulfonate) (PEDOT:PSS) with different conductivities [17][18][19] were inserted between the indium tin oxide (ITO) layer and the organic photoconductive layer as a carrier transport layer. Then, we also investigated the relationship between the concentration of R6G in poly (9,9-di-n-octylfluorenyl-2,7-diyl) (PFO) and the photoconductive characteristics of the greensensitive organic device.…”

Improved Characteristics of Fluorene‐Type Polymer Light‐Emitting Devices Based on Multilayer Formation from Polymers and Solution‐Processable Wide‐Bandgap Inorganic Copper(I) Thiocyanate with p‐Type Conduction and High Refractive Index

“…In addition, the gradual destruction of the ITO electrode due to impact occurs in OLEDs. [ 17 ] Therefore, alternative transparent electrodes are needed. In order to produce organic devices at low cost and in large quantity, shortening the process becomes necessary.…”

Organic light-emitting and photodetector devices for flexible optical link and sensor devices: Fundamentals and future prospects in printed optoelectronic devices for high-speed modulation

“…The stress tolerance of the OLEDs with ITO or highly conductive polymer electrodes [poly(ethylenedioxythiophene):poly(styrene sulfonic acid), PEDOT:PSS] as an anode has been reported [12]. Pushing tolerance tests were performed for OLEDs fabricated on polymeric substrates as shown in Fig.…”
