Rare-Earth Luminescent Materials

Dear Colleagues,

Rare-earth ions, featuring unique 4f electronic configurations, exhibit exceptional luminescent properties, including sharp emission lines, long lifetimes, and tunable emission wavelengths spanning the ultraviolet, visible, and near-infrared (NIR) spectral regions. These ions, when incorporated into various hosts, enable the design of advanced luminescent materials with tailored optical properties. Recent contributions have demonstrated the significant potential of rare-earth-doped luminescent materials in a wide range of applications, covering solid-state lighting, high-resolution displays, optical thermometry, bioimaging, and anti-counterfeiting. These materials are also increasingly explored for their role in next-generation optoelectronic devices, such as photovoltaic cells, laser systems, and advanced optical sensors.

This Special Issue, entitled “Rare-Earth Luminescent Materials”, focuses on the latest advancements in rare-earth-based luminescent materials, including, but not limited to, the fundamental mechanisms of luminescence, novel synthesis techniques, and the optimization of material properties for functional applications.

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-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Inorganics 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 2200 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.
