Special Issue Information

Dear Colleagues,

It is our pleasure to announce a new Special Issue of Materials devoted to perovskite optoelectronic functional materials and devices. New materials, new structures, and new manufacturing tools have allowed novel high-performance electronic and optoelectronic devices. We expect that the continuous progress and cross-integration in these fields will continue to lead the development of optoelectronic theory and optoelectronic applications. This issue will aim to cover the following topics:

  • Electronic, optical and structural properties of novel nanocrystals materials;
  • Physics and applications of novel devices based on perovskite material;
  • Device physics and applications (LEDs, solar cells, photodetectors);
  • Physics and applications of II-IV and III-V compound semiconductors for optoelectronics;
  • Advanced characterizations of optical and optoelectronic properties of semiconductors.

The purpose of our Special Issue is to build a platform for scholars committed to, but not limited to, the above research fields to share and exchange scientific research.

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. Materials 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 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.

Tin-based perovskite has emerged as an excellent luminescent material due to its non-toxicity and narrow bandgap compared to lead-based perovskite. However, its tin ions are easily oxidized by oxygen, which leads to increased vacancy defects and poor crystallinity, presenting a significant challenge in obtaining high-quality perovskite films. In this context, we introduced an approach by synergistically adding SnF2 and tin powder into the precursor solution to enhance the antioxidation of Sn ions. This method effectively improved the crystallinity of the perovskite films, reduced the density of defect states, and enhanced the photoluminescence performance of the films. Based on these findings, we successfully fabricated tin-based near-infrared perovskite light-emitting diodes (PeLEDs). With a 20% improvement in the Sn2+ content in the film, we achieved a threefold increase in the external quantum efficiency of the devices, reaching 3.6%. Full article
