Luminescence Properties of Nanomaterials and Nanocomposites

Dear colleagues,

One of the most intriguing goals in the field of modern nanotechnologies is the development of materials with physical/chemical properties favorable for highly efficient and color-tunable light emission. In fact, the reduction of material size to the nanometer scale brings out new properties, different from those of the macroscopic component, mainly due to quantum confinement effects and the high specific surface. These unique characteristics introduced by material downsizing open an exceptionally wide range of applications that exploit several luminescence processes: exciton or band-to-band recombination and emission from surface defects. The current research is therefore stimulated towards increasingly ambitious challenges such as the precise control of the optical properties of nanomaterials and nanocomposites by engineering their size; altering their surface by doping and functionalization; and integrating them within specific devices in the fields of optoelectronics, photovoltaics, bioimaging, lasing, and sensing.

The purpose of this Special Issue is to include experimental and/or computational studies of luminescent nanosized materials, ranging from semiconductors to insulators, both pure and alloy. A relevant focus is to highlight the state of knowledge in the manufacturing and characterization of these systems in an effort to understand their remarkable emission properties at a fundamental level and advance their potential for upcoming optical applications.

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. Nanomaterials is an international peer-reviewed open access semimonthly journal published by MDPI.
