Special Issue Information
Dear Colleagues,
Recent advances in nanostructured photodetectors have opened up new avenues for high-performance optoelectronic devices. Photodetectors play a crucial role in imaging, sensing, and communication systems, and the integration of nanostructures has significantly enhanced their responsivity, speed, and spectral selectivity. Nanostructured materials, such as quantum dots, nanoparticles, nanowires, and two-dimensional materials, enable improved light absorption, carrier transport, and photoconductive gain through quantum confinement and surface engineering. Additionally, plasmonic nanostructures and metamaterials have been employed to enhance light–matter interactions, extending detection ranges to ultraviolet, visible, and infrared wavelengths.
This Special Issue of Nanomaterials aims to highlight cutting-edge research on nanostructured photodetectors, bridging fundamental discoveries to technological innovations. We invite contributions addressing novel material designs, device engineering strategies, and mechanistic studies, as well as reviews that critically assess progress in the field. Topics of interest include, but are not limited to, the following:
- Ultra-sensitive photodetectors based on quantum-confined nanostructures.
- Wide-bandgap and narrow-bandgap nanostructured photodetectors for UV/IR sensing.
- Self-powered and energy-efficient nanostructured photodetector designs.
- Two-dimensional material-based photodetectors (e.g., graphene, transition metal dichalcogenides).
- Plasmonic and metamaterial-enhanced photodetection.
- Hybrid organic–inorganic nanostructured photodetectors.
- Scalable fabrication techniques for industrial adoption.

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.
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.
