Low-Dimensional Materials for Film-Based Opto-Electronic Devices

Dear Colleagues,

Low-dimensional materials—such as zero-dimensional quantum dots, one-dimensional nanowires, and two-dimensional layered materials—have emerged as key building blocks for next-generation opto-electronic devices due to their unique tunable properties, quantum confinement effects, and high surface-to-volume ratios. Coating technologies—including core/shell engineering, ligand exchange, encapsulation, and thin-film deposition—play a pivotal role in tuning interfacial properties, enhancing photostability, suppressing defect states, and enabling device-level integration.

This Topical Collection aims to gather original research and critical reviews at the intersection of low-dimensional materials and advanced coating technologies. We welcome contributions that explore novel synthetic strategies, innovative surface passivation methods, scalable coating processes, and structure–property–performance correlations in nanomaterial-based systems.

This Topical Collection offers a timely and comprehensive platform to highlight the convergence of materials science and surface/interface engineering through coating technologies. By fostering cross-disciplinary contributions from chemistry, materials science, physics, and engineering, the Topical Collection aims to accelerate the development of nanomaterial-based devices with enhanced efficiency, longevity, and manufacturability.

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. Coatings 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 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.
