Special Issue Information
Dear Colleagues,
The optical properties of layered van der Waals materials have been a focal point of intense exploration, largely due to the prevalence of Coulomb-bound electron–hole pairs known as excitons. Even at room temperature, these excitons exhibit a significant presence owing to their substantial binding energy. While materials such as transition metal dichalcogenides (e.g., MoS2, WSe2), post-transition metal monochalcogenides (e.g., InSe), black phosphorus, and metal-halide perovskites (e.g., MAPbI3) host Wannier excitons with radii exceeding the lattice parameters, magnetic chromium trihalides (e.g., CrBr3) are characterized by Frenkel excitons that are notably smaller, often comparable to the unit cell size. The excitonic nature of these materials extends beyond fundamental experimental investigations employing techniques such as photoluminescence or absorption. It also defines electrically driven luminescence signals observed in optoelectronic devices. Understanding these aspects is pivotal for unraveling the basic optical hallmarks of layered materials. Moreover, integrating these materials into optical devices at the laboratory scale holds significant promise for future applications.
In line with this, our Special Issue, entitled “Advances in Two-Dimensional Layered Materials: From Excitonic Complexes to Optoelectronics”, seeks to comprehensively cover the spectrum of research on excitonic complexes in two-dimensional layered materials. Emphasizing both fundamental investigations and applied research on various devices, this Special Issue aims to provide a platform for disseminating cutting-edge developments in the field.

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. Nanomaterials is an international peer-reviewed open access semimonthly journal published by MDPI.
