Abstract
A method for producing simple and efficient thermally-activated delayed fluorescence organic light-emitting diodes (OLEDs) based on guest-host or exciplex donor-acceptor emitters is presented. With a step-by-step procedure, readers will be able to repeat and produce OLED devices based on simple organic emitters. A patterning procedure allowing the creation of personalized indium tin oxide (ITO) shape is shown. This is followed by the evaporation of all layers, encapsulation and characterization of each individual device. The end goal is to present a procedure that will give the opportunity to repeat the information presented in cited publication but also using different compounds and structures in order to prepare efficient OLEDs.
Highlights
Organic electronics brings together all fields from chemistry to physics, going through materials science and engineering in order to improve the current technologies towards more efficient and more stable structures and devices
Degradation occurs when carriers injected into the device react with the organic layers resulting in the breaking of bonds and molecules
The present protocol aims to present an effective tool for the patterning, production, encapsulation and characterization of organic light-emitting diodes (OLEDs) based on small molecular-weight thermally-activated delayed fluorescence (TADF)-emitting or exciplex-emitting layers
Summary
Organic electronics brings together all fields from chemistry to physics, going through materials science and engineering in order to improve the current technologies towards more efficient and more stable structures and devices. Reports say that the OLED industry for displays may increase from the 16 billion dollars in 2016 to around 40 billion dollars by 2020 and more than 50 billion by 20263 It is finding its way into general lighting and head-mounted microdisplays for augmented-reality[4]. Applications like organic sensors for biomedical applications is more of a futuristic application at the moment, given the requirements for both high luminance and stability[5]. This trend confirms the need for improved device structures that includes more efficient molecules at less expense of natural resources. A better understanding of the inherent processes of the materials used for OLEDs is of great importance when designing these
