Special Issue Information
Dear Colleagues,
Organic Light-Emitting Diodes (OLEDs) have produced exciting achievements over the last decade. One of the most important achievements is the development of Thermally-Assisted Delayed Fluorescence (TADF)-type emitting molecules and the control of orientation of organic molecules. TADF molecules open a way to harvest both triplet and singlet excitons through fluorescence, enabling almost 100% internal quantum efficiency (IQE) using the merits of phosphorescent dyes. Furthermore, TADF molecules have shown their potential to overcome the critical issue in the present blue phosphorescent OLEDs. Next, controlling the dipole orientation of organic emitting molecules in OLEDs give a way to boost external quantum efficiency (EQE) over 40% without any external outcoupling structures. In addition, the control of the orientation and growth of organic transporting molecules is also important to achieve high mobility in organic thin-film transistors over 10 cm2/Vs. Based on the achievements, OLEDs have dominated small-sized mobile display market and they are rapidly expanding their territory toward next generation displays and lightings such as large sized flexible, stretchable displays, circuits and other device applications.
The main aim of this Special Issue is to seek high-quality submissions that highlight recent breakthroughs in OLEDs regarding molecular designs, control of intra- and inter molecular interactions, device architectures, new materials and processing, device physics, and new systems beyond OLEDs. The topics of interest include, but are not limited to:
- Organic Light-Emitting diodes (OLEDs) materials
- OLED device physics
- Thermally activated delayed fluorescence
- Molecular orientation
- Light extraction and Lightings
- Organic–inorganic hybrid LEDs
- Perovskites
- Organic thin film transistors
- Flexible displays and lightings
Manuscript Submission Information
Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.
Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Electronics is an international peer-reviewed open access semimonthly journal published by MDPI.
Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2400 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
Benefits of Publishing in a Special Issue
- Ease of navigation: Grouping papers by topic helps scholars navigate broad scope journals more efficiently.
- Greater discoverability: Special Issues support the reach and impact of scientific research. Articles in Special Issues are more discoverable and cited more frequently.
- Expansion of research network: Special Issues facilitate connections among authors, fostering scientific collaborations.
- External promotion: Articles in Special Issues are often promoted through the journal's social media, increasing their visibility.
- e-Book format: Special Issues with more than 10 articles can be published as dedicated e-books, ensuring wide and rapid dissemination.
