Recent Progress in the Fabrication of Efficient Organic Light-Emitting Diodes: Materials and Device Structures

Dear Colleagues,

Organic light-emitting diodes (OLEDs) have come a long way since they were first discovered in 1987 at Kodak. OLEDs have become an important source of lighting and display technology with high external quantum efficiency (EQE), color purity, energy saving and wavelength tunability, as well as low-temperature processability. Today, OLEDs are specifically valued in the display and lighting industries due to their promising qualities. As one of the research fields that stimulates and promotes the growth of academia and industry, OLED device technology has been constantly evolving for more than 3 decades. OLED devices have been developed based on first-generation electroluminescent materials relying on fluorescence (first generation), second-generation electroluminescent materials depending on phosphorescence, and third-generation emitters relying on thermally activated delayed fluorescence (TADF), hybrid local and charge transfer (HLCT), and hot excitons. Moreover, science and industry are currently investigating the 4th generation of OLEDs. Furthermore, aggregation-induced emission (AIE)-based OLEDs have made significant progress in the past decade. Additionally, flexible OLEDs based on biodegradable materials have also attracted the world’s attention for the development of next-generation green and flexible electronics.

Therefore, this Special Issue invites research papers, short communications, and review articles that focus on recent developments of novel materials and device architectures for the construction of efficient, low-cost, energy-saving, and eco-friendly OLEDs.

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 250 words) can be sent to the Editorial Office for assessment.

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. Micromachines is an international peer-reviewed open access monthly 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 2100 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.
