          Stanford University in the United States studies new process graphene as organic LED

          According to researchers at Stanford University in the United States, graphene can provide lower cost, thinner, and faster speed than the rare and expensive indium tin oxide (ITO) commonly used in transparent electrodes for organic LED (OLED) displays. A quick alternative to avoid the shortage of ITO and pave the way for the development of flexible displays.

          It has proven to be very difficult to make graphene directly on a large area of a€?a€?substrate. However, Stanford's research team claims to have successfully developed a cheaper, solution-based spin-coating scattering technique for making transparent graphene OLED anodes. Today's organic displays use inorganic ITO to make transparent electrodes for switching pixels. However, since this material is also used in the manufacture of LCD panels, it is costly and insufficiently supplied. And Stanford researchers say that the cost of graphene is less than one percent of ITO. In addition, graphene has higher electron mobility than ITO, making the electrode thinner, more transparent, and more conductive. These advantages greatly benefit the development of ultra-thin flexible OLED displays. In order to improve the conductivity of the material on quartz substrates, these researchers used a vacuum annealing process, but they are currently trying to eliminate this step because it is said that this improvement will make it possible to achieve low temperature in flexible plastics. A graphene electrode is fabricated on the substrate.

          The graphite oxide powder is obtained by drying an aqueous solution of graphene oxide. Redispersible in solvents such as water
