Nanomaterials and Quantum Dots: Advancements in Photocatalysis and Optoelectronics

Dear Colleagues,

Recent attention has been increasingly drawn to nanomaterials or quantum dots owing to their exceptional physical and chemical activity. Consequently, these materials have found extensive applications in various fields, including solar cells, batteries, sensors, and optoelectronic devices. Quantum dots or nanoparticles are gaining significant attention as exceptional materials for the optoelectronic field, attributed to their outstanding characteristics, including a prolonged carrier lifetime, high charge carrier mobility, and a remarkable photoluminescence quantum yield. Their quantum confinement effect, resulting from the quantum size effect, confines excitons to a small region, leading to enhanced charge dissociation in photovoltaics and enabling the precise control of optical absorption across the various wavelength regions, thus optimizing solar energy harvesting. Nanomaterials, especially metal oxides and core–shell nanocomposites, play an indispensable role in enabling crucial processes, including CO₂ reduction, gas sensing, and supercapacitors. Remarkably, nanoparticles facilitate the enhancement of electron generation, consequently resulting in the creation of additional OH radicals that substantially elevate the efficiency of the photocatalytic process.

This Special Issue aims to highlight the cutting-edge advancements in the synthesis of nanomaterials and quantum dots for application in light-emitting diodes (LEDs), photocatalysis, and biological systems. Additionally, the Issue aims to advance our understanding of systematically derived nanomaterials and quantum dots, elucidating their excitonic properties, growth morphologies, and exceptional performance in the field of energy, the environment and biological applications.

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. 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.
