Special Issue Information

Light-emitting diodes (LEDs) have reshaped the modern technological landscape, evolving from simple indicators to cornerstone components in advanced lighting, displays, and optical systems. Rooted in advances in wide-bandgap semiconductors such as GaN and AlN, as well as organic emissive materials, both inorganic LEDs and OLEDs have achieved remarkable progress in efficiency, stability, and integration. The continual development of epitaxial growth methods, quantum structure design, and light extraction techniques has enabled LEDs to reach remarkable levels of performance across the visible and ultraviolet spectrum. Furthermore, the emergence of mini/micro/nano-LEDs, perovskite emitters, and flexible optoelectronics opens new frontiers in high-performance display systems, AR/VR, optical communication, and biomedical interfaces. At the intersection of materials science, device physics, and system engineering, the LED field embodies interdisciplinary innovation with a global impact. This Special Issue aims to provide a comprehensive platform for the latest advances spanning the full LED technology spectrum, from fundamental material development to device integration. By bringing together insights across materials science, physics, and engineering, this collection will highlight the interdisciplinary progress that drives the next generation of LED technologies. We welcome original research articles, reviews, and perspectives that reflect both fundamental breakthroughs and translational innovations.

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. Materials 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 2600 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.
