Dear Colleagues,

Quantum dots (QDs) are unique material structures in which the carriers are three-dimensionally confined and the intrinsic properties are altered by quantum confinement effects, which are exploited by controlling their size. The QDs research field has been a hot topic in fundamental studies for several decades and has found applications in various fields, including displays, illuminations, renewable energy devices, photodiodes, photoresists, image sensors, biomedical applications, and so on. With the mass production of QDs and further understanding of their photophysical and photochemical properties, many industries have been involved in the development of quantum-dot device techniques and will open a market in this field.

This Special Issue aims to provide recent, informative, QD-related resources for readers by addressing a broad range of topics, from QD materials chemistry and characterization to processing and device fabrication. It will focus not only on the synthesis of QD materials with various compositions, such as II–VI, III–V, perovskite, and carbon families; core/shell hetero-structural engineering; and surface modification/encapsulation; but also on their versatile applications, such as down-conversion-based and electroluminescence-based light-emitting diodes for display/lighting devices; luminescent solar concentrators; and biological labels.

We believe that this Special Issue on QDs will provide an opportunity to circulate innovative ideas and technologies on these emerging topics and contribute to the dissemination of expertise for young and leading researchers in the QD-related field.

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. Crystals 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 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.
