Special Issue Information
Dear Colleagues,
The outstanding optoelectronic properties of lead halide perovskites (LHPs) have enabled many promising optoelectronic applications in high-performance solar cells and beyond. However, the presence of toxic lead (Pb) impedes the practical applications of LHPs, particularly for consumer electronics. Perovskite-inspired materials (PIMs), both three-dimensional perovskite derivatives, namely, Sn(II) halide perovskites and halide elpasolites, and electronic analogs (i.e., zero-, one-, and two-dimensional metal halides comprising cations such as Ag+, Na+, Bi3+, Sb3+, In3+, Sn4+, and Ti4+) have emerged as low-toxic alternatives to LHPs. Yet, the performance of PIMs in photovoltaics, light-emitting diodes, and other optoelectronics is far inferior to that of LHPs, which has been attributed to their low photoluminescence quantum yields, high defect concentration, suboptimal thin film morphology, and poor selection of charge transport layers in the corresponding devices. Overall, the insufficient understanding of the physics and chemistry of these materials is the key reason for the limiting factors in PIM-based devices.
In this context, the present Special Issue will focus on the synthesis, photophysics, and material and device engineering of lead-free PIMs for an improved understanding of the fundamental aspects, enhanced device performance, and the discovery of unexplored applications. This Special Issue invites original research articles (experimental and theoretical), perspectives, and reviews to demonstrate state-of-the-art research on the topics below:
- Synthesis, structural, and photophysical properties of novel PIMs (thin films, solid powders, and colloidal nanocrystals);
- Microstructural engineering, defect chemistry, and device physics;
- Photovoltaics (solar cells and indoor photovoltaics), light-emitting diodes, photodetectors, memristors, and photocatalysis;
- Photonic and other novel functional 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 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. Nanomaterials is an international peer-reviewed open access semimonthly journal published by MDPI.
