Quantum Dots (QDs), which were originally identified as tiny semiconductor nanoparticles (with a size of several nanometers), from the moment of their appearance in the literature in the mid-1980s, immediately occupied a very important place in nanoscience and nanotechnology. A special property that determined the success that QDs have enjoyed is the tunable fluorescence (or photoluminescence). The tunable fluorescence of QDs makes them uniquely suited to various applications. In particular, QDs turned out to be indispensable in bioscience and biotechnology, where they are used for fluorescent imaging of various bio-objects (from cells to micro RNA). Of course, fluorescent imaging is not the only application of QDs. They are widely used in CERS, the development of new lasers and ultrasensitive sensors, and many other fields.
However, the concept of a QD as a semiconductor particle has recently undergone a significant change after it turned out that the smallest particles of not only semiconductors but also some metals (such as Ag and Si) have the property of tunable fluorescence. A significant change in the study of QDs occurred with the discovery of carbon QDs, which, in contrast to semiconductor QDs, show low toxicity, have more stable fluorescence, and are significantly cheaper to produce. More recently, research has started to shift towards another new very promising object: graphene QDs.
This Special Issue of Nanomaterials will attempt to cover the most recent findings in QD science and applications. Studies that describe new synthesis methods, fabrication techniques and approaches, characterization techniques, materials as possible candidates for QDs, and properties of different QDs will be considered. Of course, applications of QDs in different fields of science and technology will be welcome.

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 papers will be 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 monthly journal published by MDPI.
