Special Issue Information
Dear Colleagues,
Photon upconversion converts low-energy excitation into higher-energy emission, offering bright, spectrally sharp, and photostable signals. Lanthanide-doped nanocrystals have become a leading platform for this process, enabling efficient anti-Stokes emission through well-defined 4f energy levels. These nanoparticles now support a wide range of technologies—from deep-tissue imaging and ultrasensitive biosensing to optical security, displays, and data handling—and continue to gain importance as nanoscale synthesis and surface engineering advance. This Research Topic highlights recent progress in upconversion nanosystems. We welcome original research, mini-reviews, and full reviews covering materials design, synthesis, characterization, optical behavior, upconversion mechanisms, energy-transfer processes, and emerging applications of UCNPs. Contributions on related photon-upconversion materials and technologies are equally encouraged.

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-anonymized 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.
