Fluorescent Quantum Dot Nanomaterials

Dear Colleagues,

Photoluminescent carbon quantum dots have excellent optical properties, good biocompatibility, high chemical stability as well as low toxicity. As new-generation photoluminescent nanomaterials, they have extensive potential applications in bioimaging, optoelectronics, photocatalysis and solar energy harvesting. So, great efforts have been exerted on the preparation of carbon quantum dots from a variety of carbon precursors by various methods, such as arc discharge, electrochemical oxidation, combustion, thermal decomposition or oxidation, and microwave-assisted pyrolysis. However, most of these routes suffer from expensive equipment, harsh synthetic conditions, and tedious processes, leading to manufacturing difficulties and high costs for large-scale production. Moreover, the resultant carbon quantum dots usually show low photoluminescence quantum yields, which inhibits their widespread use. It is critical to search for new carbon sources to synthesize carbon quantum dots with high photoluminescence for application in various fields.

The present Special Issue of Nanomaterials is aimed at presenting the current state-of-the-art in the use of quantum dots as fluorescent materials in bioimaging, optoelectronics, photocatalysis and solar energy harvesting. In the present Special Issue, we invite authors to contribute original research articles and review articles covering the current progress on fluorescent or phosphorescence quantum dot materials.

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.
