Metal halide perovskites have attracted great attention in lighting due to their excellent photophysical properties: broad absorption range; high absorption coefficient; a characteristic narrow emission band assigned to the direct exciton recombination, and a small energy shift between the absorption and emission peak positions. These materials can also exhibit a broad and strong Stokes-shifted emission, which is relevant for white-light generation. There is some controversy about the origin of this broad emission, and it has been ascribed to self-trapped excitons (STE) due to the strong carrier–phonon interactions, and/or to defect/impurity-bound excitons in-gap states.
This Special Issue will report on how to prepare customized emissive perovskite materials by providing experimental and theoretical studies that can help to understand the relationship between the observed broad emission and the perovskite’s dimensionality, composition, and crystal structure distortion. This knowledge will boost the development of efficient, broad-emissive perovskites of interest for white-light illumination, among other applications.
We encourage authors to submit studies related to this topic, involving lead and lead-free halide perovskites (solids and colloids) of different dimensionality (3D, 2D, 1D, and 0D) and composition, as well as metal-doped perovskites. It is highly recommended that authors include photoluminescence efficiency, as well as thermal, chemical, and photochemical stability information of the materials. Original contributions and/or perspectives are welcome.

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 papers will be 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 monthly 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 2200 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.
