Special Issue Information

Dear Colleagues,

Materials research is crucial in the development of devices for applications in several areas where photonics is present, such as photovoltaics, displays, biophotonics, integrated optics, nonlinear optics, optical sensors, and communications.

In this Special Issue, we are interested in exploring materials science and technology research, focusing on photonic applications. Authors are encouraged to submit their works comprising the design, synthesis, fabrication, and/or characterization of novel materials for photonics. This may include lanthanide-doped materials, quantum dots, disordered materials for random lasers, nonlinear optical materials, plasmonics, nanocomposites, flexible substrates for photonics, photonic crystals, metamaterials, graphene and 2D materials, or others. The key aspect of this issue is to show the importance of materials development for the photonics research and industry.

We expect to attract contributions from world-leading experts in the area of materials reseach for photonics in an effort to offer an overview of the field, with a particular emphasis on major advances and outstanding challenges.

All papers need to present original, previously unpublished work and will be subject to the normal standards and peer-review processes of the journal. Manuscripts must be prepared according to the usual standards for submission to Applied Sciences and uploaded through the MDPI electronic submission system.

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. Applied Sciences 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).

The synthesis of carbon-based quantum dots has been widely explored in the literature in recent years. However, despite the fact that synthesis processes to obtain highly efficient carbon quantum dots (CQDs) and graphene quantum dots (GQDs) with redshifted photoluminescence (PL) have been improved, few works have exploited sucrose in the synthesis of GQDs with high PL efficiency. In this work, sucrose, which is a widely available non-toxic saccharide, was used as a precursor of GQDs. Initially, sucrose was carbonized in sulfuric acid, and thereafter, the material obtained was treated in dimethyl sulfoxide (DMSO). Nitrogen doping was also performed in this work through an additional step involving the treatment of carbonized sucrose in nitric acid reflux. Nitrogen-doped GQDs (N-GQDs) showed tunable PL dependent on the excitation wavelength. It was also verified that the intensity of the emission in the red region was much higher in the N-GQDs in comparison with that in undoped GQDs. X-Ray Diffraction, Raman, FTIR, TEM, and AFM analyzes were also performed to obtain greater structural details of the obtained GQDs. Full article

Co-doped Zinc selenide (ZnSe) is a promising material because of a high photoluminescence efficiency and wide spectral range emission in the visible region. In this work, ZnSe and Eu3+/Yb3+ co-doped ZnSe crystals were grown by the chemical vapour transport method. Photoluminescence and optical measurements revealed the effect of trivalent rare earth Eu3+/Yb3+ ions on the emission of new lines with enhancement intensity. In the photoluminescence spectrum, some sharp and intense lines were observed that allow for the possibility of covering a broad emission range. Moreover, the optical measurement showed a lower bandgap compared to that of pure ZnSe bulk crystal. This material is suitable for developing optoelectronic devices, which can emit light in the visible and near infrared range with an improved emission efficiency and wide tunability. Full article
