Molecular Spectroscopy for Applications in Material Science: Hybrid Organic–Inorganic Perovskites and Related Compounds

Dear Colleagues,

Hybrid organic–inorganic compounds have been the subject of intense studies because their diverse structural and chemical variability offers unlimited opportunities for tuning their physical and chemical properties by chemical modification of organic and/or inorganic parts. One of the most important sub-groups of organic–inorganic hybrid materials are metal halides, particularly lead halide and lead-free perovskites, which have proven to be a fascinating class of semiconductors possessing excellent optoelectronic properties.

Understanding the optical properties of these materials requires the application of emission and electron absorption spectroscopic methods. However, luminescent and optoelectronic properties of hybrid materials are also strongly influenced by the lattice dynamics. Furthermore, the dynamics of the organic cations plays a major role in phase transitions and the appearance of useful properties such as ferroelectricity or nonlinear optical properties. It is, therefore, of great interest to perform studies of hybrid organic–inorganic materials, especially those undergoing order–disorder phase transitions, using various spectroscopic methods that have different probing length scales and sensitivities.

This Special Issue aims to act as a forum for the dissemination of the latest information on the application of spectroscopic methods (e.g., optical, Raman, IR, terahertz, NMR, EPR, and dielectric) in studies of hybrid organic–inorganic compounds including lead halides and lead-free perovskites. We encourage authors to submit manuscripts in the form of a research paper, review, or communication. All aspects embracing the structural, luminescent, optical and dielectric properties as well as phase transition mechanism, lattice dynamics and electron–phonon coupling will be covered.

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 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. Molecules 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 2700 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.
