Special Issue Information

Dear Colleagues,

Optoelectronic functional thin films have always been the main research direction in the fields of physics, chemistry, biology, engineering, and manufacturing. This Special Issue mainly collects related work in the field of photoelectric research, such as luminescence, power generation, energy storage and conversion, imaging, metamaterials, and metastructures. Especially in recent years, the above-mentioned optoelectronic thin films have made significant progress in these fields, and the scientific as well as technological progress brought about by them have obviously changed people's living habits. There is still a lot of work to be performed in these areas, and it is still necessary to delve into the essential factors and internal mechanisms of devices that affect optoelectronic performance, after which the relationships between materials, structures, and properties can be revealed. We expect continued advancement and cross-integration in these areas in order to continue to lead the way in optoelectronic theory and optoelectronic applications. Our Special Issue mainly aims to build a platform for scholars who are committed to engaging in, but not limited to, the above research fields in order to share and exchange scientific research. We look forward to receiving your submissions!

You may choose our Joint Special Issue in Coatings.

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. Optics is an international peer-reviewed open access quarterly 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 1200 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.

YbxEryZnO thin films with a low concentration (x = 5%, y = 0, 1, 3%) were made on glass substrates using the spray pyrolysis method. The films were characterized through the use of specific techniques to investigate their structural, optical, and electrical properties. The XRD structural analysis of the films revealed that they are polycrystalline with a hexagonal wurtzite structure and a preferential orientation in the (002) direction. The optical characterization of the co-doped layers in the range of 200 to 800 nm revealed that co-doping had a significant impact on the values of transmission. A well-defined peak in the infrared domain centered around 980 nm was observed in photoluminescence measurements. This peak signifies the transition between the electronic levels 2F5/2 (ground state) and 2F7/2 (excited state), proving that photons are efficiently transferred between the ZnO matrix and the Yb3+ ion. All layers exhibited n-type conduction and an electrical resistivity decrease to 6.0 × 10−2 Ω cm according to Hall effect measurements at room temperature. Full article
