Dear Colleagues,

The synthesis of luminescent materials has attracted extensive research for multiple applications, including more efficient photovoltaic devices, electro-optical and opto-electronic conversion, as well as light-emitting devices (LED). Nanostructured materials, quantum dots (QDs), thin film multilayers, and even organic-inorganic hybrid composites are some of the alternatives that have been explored to obtain more efficient devices, including for flexible applications. The modulation of bandgap energy through the QD size, the presence of different luminescent defects by changing the stoichiometry of the material, or the energy transfer phenomenon offers new ways to control the luminescence of a LED with a specific wavelength or at a broad spectrum, the latter for white light sources. Despite enormous efforts denoted by countless studies published on the development of different luminescent materials, it is still necessary to solve problems as basic as the need for a better understanding of the emission mechanisms to obtain an efficient electroluminescent transformation process.

In order to move forward in the development, understanding, and application of such materials, the purpose of this Special Issue is to review and present the latest knowledge on luminescent materials for their application in light-emitting devices. Authors are encouraged to submit original research as well as review articles on the aforementioned subjects.

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. Micromachines 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.
